The measure of the following angles are;
- b° = 87°. option C
- 60°. option D
- 58°. option C
- 65°. option D
- 62°. option C
What is the measure of the missing angles?
9.
b° + 93° = 180° (supplementary angles)
b° = 180° - 93°
b° = 87°
11.
60° + 60° + x° = 180° (sum of angles in a triangle)
120° + x° = 180°
x = 180 - 120
x = 60°
12.
45° + 77° + x° = 180° (sum of angles in a triangle)
122° + x° = 180°
x = 180 - 122
x = 58°
13.
80° + 35° + x° = 180° (sum of angles in a triangle)
115° + x° = 180°
x = 180 - 115
x = 65°
14.
32° + 86° + x° = 180°
118° + x° = 180°
x = 180 - 118
x = 62°
