Question

What is the measure of angles 5 and 6.

Answer 1

22° and 158°

Explanation:

the sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles in the triangle from 180

∠5 = 180° - (90 + 68)° = 180° - 158° = 22°

∠5 and ∠ 6 form a straight angle, thus the angles are supplementary

∠6 = 180° - ∠5 = 180° - 22° = 158°

Answer 2

5

180°-(90°+68°)=180°-158°=22°

6

180°-22°=158°
