Answer:

so x = 20 , y = -21 , which is in quad IV

r^2= 400+441 = 841

r = √841 = 29

then cos Ø = 20/29

sec Ø = 29/20 = 1.45

the two figures below are congruent. find the measure of the angle that isn't labeled on either figure.
marin [14]
Hello!

Since the shapes are congruent the angles are the same

The angles are 133, 41, 86

The angles in a quadrilateral add to 360

We subtract the numbers from 360 to get the measure of the unknown angle

360 - 133 - 41 - 86 = 100

The answer is 100°

Hope this helps!

Plot all ordered pairs for the values in the domain D: (-8, -4, 0, 2, 6)
alexdok [17]

All ordered pairs for the values in the domain will be (-8, -3), (-4, -1), (0, 1), (2, 2), and (6, 4).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space.

The function is given below.

y = (1/2) x + 1

Then the domain is D: (-8, -4, 0, 2, 6)

Then the ordered pair will be

For x = -8

y = (1/2)(-8) + 1

y = -3

For x = -4

y = (1/2)(-4) + 1

y = -1

For x = 0

y = (1/2)(0) + 1

y = 1

For x = 2

y = (1/2)(2) + 1

y = 2

For x = 6

y = (1/2)(6) + 1

y = 4

All ordered pairs for the values in the domain will be (-8, -3), (-4, -1), (0, 1), (2, 2), and (6, 4).

More about the coordinate geometry link is given below.
