Answer:

w= 27.47 degree

x=9.99 cm

y=12.02 cm

Step-by-step explanation:

The value of w:

In a right-angled triangle [tex]\tan \theta = \frac {\text{Perpendicular}}{\text{Base}}[/tex]

[tex]\tan w = \frac {\text{Perpendicular}}{25+9}\;and \; \tan 63 = \frac {\text{Perpendicular}}{9}[/tex]

So, [tex]34 \tan w = 9\tan (63)[/tex]

[tex]\tan w = (9/34)\tan(63)=0.52 \\\\w=\tan^{-1}(0.52) \\\\[/tex]

w= 27.47 degree

The value of x:

In a right-angled triangle [tex]\sin \theta = \frac {\text{Perpendicular}}{\text{Hypotaneous}}[/tex]

sin (27) =x/22

x= 22sin(27)

x=9.99 cm

The value of y:

By using Pythagoras theorem,

[tex]y^2+y^2=17^2 \\\\2y^2 = 289 \\\\y^2 =289/2= 144.5 \\\\y=\sqrt {144.5} \\\\[/tex]

y=12.02 cm

Answer: Last Option (Red In Colour)

Reason: Since Point Slope Form is y -y1 = m(x-x1), We just plug in the numbers. Four will go into the x1 spot, and Zero will go into the y1 spot, and 1/2 in the m spot since it's the slope. So, after plugging everything in, the equation is y - 0 = 1/2 ( x- 4)

I hope this helps, and Happy Holidays! :)

Answer: the answer is 10.54 I think

Step-by-step explanation:

Answer:

m∠ABE = 62°

Step-by-step explanation:

Since, the given quadrilateral is a kite, diagonals will intersect at 90°.

Therefore, m∠AEB = m∠CEB = 90°

m∠BAE = 28° [Given]

m∠BCE = 58° [Given]

From ΔABE,

m∠BAE + m∠BEA + m∠ABE = 180°

28° + 90° + m∠ABE = 180°

m∠ABE = 180° - 118°

             = 62°

Therefore, measure of angle ABE = 62°.

Answer:

slope- intercept form is

y=mx+b

m= slope

b= y-int  

looking at the chart we can see that the graph goes up 11 and right 6

so we now have

y= 11/6x+b

we could also do

m=(y2-y1)/(x2-x1) using our points

m=(21-10)/(-3-(-9)

m=11/6

then we can use an x value and its corresponding y value from the equation to find b

I will use the points -9,10

10= 11/6(-9)+b

10=-16.5+b

+16.5   +16.5

26.5=b

so your full equation is:

y=11/6x + 26.5

Using the trigonometric circle, it is found that the correct option regarding the terminal point and sin ø is given by:

A. Terminal point (0,-1); sin Ø=-1

It is a circle of radius 1 that contains the following set of points:

[tex](x,y) = (\cos{(\phi)}, \sin{(\phi)})[/tex]

The sine of 270º is of -1, hence the cosine is 0, which means that the correct option is:

A. Terminal point (0,-1); sin Ø=-1

Answer:

Samantha's age = 27 years

Step-by-step explanation:

As Samantha is one year less than twice her brother Jack’s age.

As the sum of their ages is 41.

Thus, the equation become

x+2x-1 = 41

3x-1 = 41

3x = 42

Dividing both sides by 3

x = 14

It indicates that Jack's age = 14 years

Therefore,

Samantha's age = 2x-1 = 2(14)-1 = 27 years

Answer:

Whole numbers are also integers. There are other integers which are the opposites of the whole numbers (−1, −2, −3, ...). These negative numbers lie to the left of 0 on the number line. Integers are the whole numbers and their opposites.

Answer:

x - 10y = -59

(+)-4x + 10y = 86

-3x = 27

x = -9

substitute x into x - 10y = -59

-9 -10y = -59

-10y = -50

y = 5

   /____________________________\

N                                                                   O

Now, we see line NO. The angles that include line NO would be angle MNO and angle MON.

For question number 4:

We can see that there is a tick mark on side AC and side DF, meaning those two sides are congruent.

We then see that angle A is congruent to angle D, since there is that little curve mark, showing they are congruent.

Last, we see that they both triangles have 90 degree angles, shown with the square on the corner of the triangle..

Using the AAS Postulate (Angle Angle Side), we can say that triangle ABC is congruent to triangle DEF.

Step-by-step explanation:

There are 84% out of 225. First find 10%. To do that divide the number by 10, so 225 ÷ 10 = 22.5 Next, do 22.5 x 8. Then you have 80%. Now, all that is need ed is the 4%. To get that, divide 225 by 100. Multiply the answer by 4 to get the 4%. Add the 80% and the 4% to get your answer. I really hope this helps. answers
