Question

Write an equation, find the measure of angle 1, how do you know?

Answer 1

Angle 1 is 180-65.6 and that is because one line is 180 so you would subtract from the angel it gives you which would leave ____ as your answer

Answer 2

anyhow, just like you saw on the previous posting, is the same thing pretty much.

a)

∡1 + ∡2 = 180°   <---- recall a flat-line is 180°

b)

∡1 + 65.6 = 180

∡1 = 114.4°

c)

∡1 and ∡2 are supplementary angles, and supplementary angles sum up to 180°.
