Any triangle's three interior angles add up to 180 degrees, according to the Triangle Sum Theorem.

Any triangle's three interior angles add up to 180 degrees, according to the Triangle Sum Theorem. m∠1+m∠2+m∠3=180∘.

Here,

According to the triangle sum theorem, a triangle's total angles equal 180°. Therefore, using the Substitution property

=> (3x)° + 90° + (x+10)° = 180°,

=>  m(A,B,C) = 180.

To find x, combine similar terms to get

=> 4x + 100 = 180. Then, using the subtraction condition of equality, convert => 13 1/2 to 80.

=> Finally, divide 80 by  5 ( 13 1/2) to find x.

The substitution property may be used to get the measure of the angle A, yielding mA = 5 ( 13 1/2) °.

When the expression is finally simplified, m < A = 66 2/3.

Let f be a function defined on all of that satisfies the additive condition is,

It is given that:

f: R → R is a continuous function such that:

[tex]f(x+y)[/tex] = [tex]f(x) + f(y)[/tex]    ∀  x , y ∈ R  (Equation-1)

Now, let us assume f(1)=k

Also,

f(0) = 0( Since, f(0)=f(0+0)

That is,

f(0)=f(0)+f(0)

By using property (1)

Also,

f(0)=2f(0)

That is,

2f(0)-f(0)=0

That is,

f(0)=0  )

Also,

f(2)=f(1+1)

That is,

f(2)=f(1)+f(1)         ( By using property (1) )

i.e.

f(2)=2f(1)

That is,

f(2)=2k

Similarly for any m ∈ N

f(m)=f(1+1+1+...+1)

That is,

f(m)=f(1)+f(1)+f(1)+ ....... +f(1) (m times)

That is,

f(m)=mf(1)

That is,

f(1) = n [tex]f(\frac{1}{n} )[/tex]

f(1) = k

[tex]f(\frac{1}{n} )[/tex] = k * [tex]\frac{1}{n}[/tex]

Also,

when x∈ Q

Then,

[tex]f(\frac{p}{q})[/tex] = [tex]f(\frac{1}{q} )+ f(\frac{1}{q} )+ .....f(\frac{1}{q} )[/tex]

[tex]f(\frac{p}{q})[/tex] = p * [tex]f(\frac{1}{q} )[/tex]

[tex]f(\frac{p}{q})[/tex] = [tex]p\frac{k}{q}[/tex]

[tex]f(\frac{p}{q})[/tex] = [tex]k\frac{p}{q}[/tex]

So,

[tex]f(x) = kx[/tex] for all x belongs to Q

Now, as we know that:

Q is dense in R.

So Э x∈ Q' such that Э a seq < [tex]x_{n}[/tex] >  belonging to Q such that:

[tex]a_{n}[/tex] belongs to Q,

[tex]a_{n}[/tex] ⇒ [tex]\alpha[/tex]

[tex]f(a_{n} )= ka_{n}[/tex]

k [tex]a_{n}[/tex] ⇒ [tex]f(\alpha )[/tex]

k [tex]a_{n}[/tex] ⇒ k [tex]\alpha[/tex]

This means that:

[tex]f(\alpha )[/tex] = k [tex]\alpha[/tex]

This means that:

The value of x and y in right angle triangle is  16√2 and 16

What is a Right Angle Triangle ?

A right triangle is a triangle having one right angle or two perpendicular sides. It is also referred to as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle. The relationship between the sides and various angles of the right triangle serves as the basis for trigonometry.

The Pythagorean theorem, often known as Pythagoras' theorem, in Euclidean geometry relates the three sides of a right triangle. This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

In the triangle 2 angles are 90° and 45° respectively.

The third angle is  = 180°+90°-45°=45°

The triangle is issosceles triangle

So the side which is not x is 16.

Now by using Pythagoras Theorem

x = √16^2+16^2 = 16√2

The value of x is 16√2

The value of y is y^2 + 16^2 = 16√2^2

y^2 = 512 - 256

y^2 = 256

y = 16

a) The total cost of purchasing the car that is worth $32,000 with the harmonized sales tax (HST) of 13% is $36,160.

b) By leasing the car instead of purchasing it outright, the customer will save $14,760.

c) The lease options for the lessee after returning the car include:

A lease is a financing option for the use of capital assets.

With a lease, the lessee uses the asset for a specific period and the lessor receives periodic payments.

There are operating and finance (capital) leases.  Though, under new accounting standards, all leases are to be classified as finance leases.

Value of the car = $32,000

Harmonized Sales Tax (HST) = 13%

Cost of the car with HST = $36,160 ($32,000 x 1.13)

Down payment = $1,000

Financing part = $35,160 ($36,160 - $1,000)

Installment payments = 48

Periodic payments = $425

Total lease cost = $21,400 ($1,000 + 48 x $425)

Savings (advantages) from leasing = $14,760 ($36,160 - $21,400)

Answer and explanation: The equation for the slope-intercept form is y=mx+b. M represents the slope and b is y-intercept/when x= 0.

We have to arrange the given equation into the form y=mx+b.

3x+2y=-14, We want to somehow isolate y.

2y=-14-3x, We can move all the terms that don't have y to the right

y=(-14-3x)/2, We can get rid of the 2 by dividing by 2 on both sides

y=-7-(3/2)x, We can distribute the division by 2 to both terms on the right

y=-(3/2)x-7, We can now just rearrange the terms

The equation is now in the form y=mx+b as -3/2 is m and -7 is b. Your answer to the first question is A.

For part B, we can use the equation for part A. We know m or the slope is -3/2 so our answer is also A.

The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of different outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics refers to the study of events subject to probability.

The ratio of all potential cases to the number of cases that are favorable to an event determines its likelihood when there is no reason for us to believe that any one of these circumstances will happen more frequently than any other, making them all equally likely.

The likelihood that an event will occur is quantified by probability. The probability of an event is the relative frequency throughout time of that event. Probabilities are all numbers between 0 and 1, inclusive—that is, any numbers between 0 and 1.

On solving the provided question we can say that the Measure of complementary angles   ∠ZY is 40 degrees.

When the sum of the measurements of two angles is 90 degrees, they are said to be complimentary.For instance, the angles of 30 and 60 degrees are supplementary. A supplementary angle is two angles combined to make a 180 degree angle, while a supplemental angle is two angles combined to make a 90 degree angle. Two angles are referred to as complimentary if their total is 90 degrees. Alternatively said, a right angle is created by the complementary angles (90 degrees).

Since ∠ZS and ∠ZY are complementary,

∠ZY+∠ZS=45                                                                                       We also have another relation which says

∠ZS=2∠ZY -30

Substituting 2. in 1. gives

∠ZY+2∠ZY -30=90

3∠ZY=120

∠ZY=40
