1 and 2 are complementary angles. 1 and 3 are vertical angles. If m2=52, what is the measure of the SUPPLEMENT to angle 3?

If angle 1 and angle 2 are complementary, then they add up to 90 degrees. We are given that angle 2 equals 52 degrees.

So we subtract and get our

38

That's NOT the final answer.

The next step is:

Angle 1 and angle 3 are vertical angles.

Vertical angles are congruent.

So if angle 1 is 38, then angle 3 is also 38.

Now, supplementary angles add up to 180 degrees.

So that's the

180-38=142

142 is the supplement of angle 3.

Hope it helps! :)

maybe i can

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
