1800
The measure of ∠6 if ∠4 is 80 degrees? How do you know?

80 degrees
∠6 and ∠4 are alternate exterior angles
Find the value of y

The measure of each interior angle of a decagon
144 degrees
The sum of these two angles is equivalent to the exterior angle
What is nonadjacent, interior angles
Measure of ∠5 if ∠3 is 120 degrees. How do you know?
![]()
60 degrees.
∠3 and ∠4 are supplementary so ∠4 = 60; ∠4 and ∠5 are alternate interior angles, which are congruent.
OR
∠3 and ∠6 are alternate interior angles so ∠6= 120; ∠6 and ∠5 are supplementary angles, so ∠5=180-120
