ANGLE RELATIONSHIPS PROBLEM SOLVING Answer Key
Answer Sample Work
1. The measure of ∠ABE is 78°. 𝑥 + 102 = 180; 𝑥 = 78
2. The measure of the angle given by the
opening of the scissors is 68°.
2𝑥 + 112 = 180 2𝑥 = 68 𝑥 = 34
3. The value of x is 10. 6𝑥 + 1 + 29 = 90 6𝑥 + 30 = 90 6𝑥 = 60 𝑥 = 10
4. The soccer ball hits the floor at a 46° angle. 𝑥 + 𝑥 + 88 = 180 2𝑥 + 88 = 180 2𝑥 = 92 𝑥 = 46
5. The measure of ∠𝐴 is 83° and the measure of ∠𝐵 is 97°.
𝑥 − 10 + 𝑥 + 4 = 180 2𝑥 − 6 = 180 2𝑥 = 186 𝑥 = 93 ∠𝐴 = 93 − 10 = 83 ∠𝐵 = 93 + 4 = 97
6. The value of x is 41°
𝑥 + 2 = 43 𝑥 = 41
7. The angles are supplementary. The value of x is 154°.
𝑥 + 5 + 21 = 180 𝑥 + 26 = 180 𝑥 = 154
8. The measures of the angles are 15° and 75°. 𝑥 + 5𝑥 = 90 6𝑥 = 90 𝑥 = 15 5𝑥 = 75
9. The measure of the larger angle is 108°. 2𝑥 + 3𝑥 = 180 5𝑥 = 180 𝑥 = 36 𝑙𝑎𝑟𝑔𝑒𝑟 𝑎𝑛𝑔𝑙𝑒 = 3𝑥 = 108
10. The measure of ∠1 is 133°. The measure of ∠2 is 47° and the measure of ∠3 is 43°.
𝑚∠1 47 + 𝑥 = 180; 𝑥 = 133 𝑚∠2 133 + 𝑥 = 180; 𝑥 = 47 𝑚∠3 47 + 𝑥 = 90; 𝑥 = 43
