In triangle ABC, the sum of the measures of angle A and angle B is 57°. What is the measure of and C?

Answer:

x = 65

Step-by-step explanation:

straight line = 180 degrees

so

180 - 165 = 25

90 + 25 = 115 degrees

180 - 115 = 65 degrees

so

x = 65

Step-by-step explanation:

9(x + 10 ) -99

9x + 9 × 10-99

9x - 9

Answer:

9(x-1)

Step-by-step explanation:

9(x + 10) - 99​

=> 9x + 90 - 99

=> 9x - 9

=> 9(x-1)

Answer:

[tex] \frac{2}{3} \\ \\ \frac{2}{2} \\ \\ \frac{4}{3} [/tex]

Step-by-step explanation:

I hope that is useful for you :)

Answer:

For example 1/1, 2/3 and 4/3

Step-by-step explanation:

There is a great way to generate rational numbers between other rational numbers using:

[tex]\textrm{If:~~~~~~} \frac{a}{b} < \frac{c}{d}\vspace{7pt}\\\textrm{Then:~} \frac{a}{b} < \frac{a+c}{b+d} < \frac{c}{d}[/tex]

So we know that (1+3)/(2+2) is between 1/2 and 3/2 without checking.

(1+3)/(2+2) = 1/1, so we got our first rational number.

Lets continue by finding numbers between 1/2 and 1/1; and 1/1 and 3/2

(1+1)/(2+1) = 2/3

(1+3)/(1+2) = 4/3

We could also look for a number between 1/2 and 2/3 and find

(1+2)/(2+3) = 3/5

And so on, so forth :)

Answer:

Step-by-step explanation:

It is a right triangle, so use the Pythagorean Theorem to solve for x.

x² +  8² = 11²

x² = 11² - 8² = 57

x = √57

The expression showing the number of students in the drama club the next year is 15+d.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, there are 20 students in a drama club,

5 of them will leave in next year, and d students will join,

We are asked to construct an expression to represent the total number of students in the drama club next year.

So, the present number of students in the club = 20

After next year = 20-5 = 15

After the joining = 15+d

Hence the expression showing the number of students in the drama club the next year is 15+d.

Answer: 0 < x < 5.6

Step-by-step explanation:

The sides of triangle:

Any two sides added together have to be larger than the third side

So:

2.8 - 2.8 < x < 2.8 + 2.8

0 < x < 5.6

Answer:

B

Step-by-step explanation:

A function can not have the same x-values but can have the same y-values. Because option B uses 0 as its x-value more than once, option B does not represent a function.

Answer:

3

Step-by-step explanation:

150-94=56

this means we have 56 dollars remaining

Step-by-step explanation:

32+26=58

32-26=6

Answer:

The first number is 32 and the second is 26

Step-by-step explanation:

Let the two numbers be represented by x and y

1) x + y = 58

2) x - y = 6

x = 6 + y, we'll use put this in the first equation.

x + y = 58

6 + y + y = 58

6 + 2y = 58

2y = 58 - 6

2y = 52

2. 2

y=26, now let's find x, again use the first equation

x + y = 58

x + 26 = 58

x = 58 - 26

x = 32

An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,

V ∝ h(r²)

Also, k is the constant of proportionality, therefore, the equation now can be written as,

V = k×h×r²

Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

Answer:

m∡BCA = 57°

Step-by-step explanation:

find 'x' by adding all expressions and setting them equal to 360°

9x+1 + tx+12 + 10x-37 = 360

24x = 384

x = 16

Substitute 16 into 10x-37

160 - 37 = 123

m∡BCA is supplemental with 123°, therefore it measures 57°
