Answer:
(5) 84° and 96° ; (6) 40° and 50°
Step-by-step explanation:
5) <em>Supplementary angles are in the ratio 7 : 8</em>
So 7x + 8x = 180°
15x = 180
x = 180/15
x = 12
The angles are 7x = 7 * 12 = 84° ; 8x = 8 * 12 = 96°
6) <em>Complementary angles are in the ratio 4 : 5</em>
So 4x + 5x = 90°
9x = 90
x = 90/9
x = 10
The angles are 4x = 4 * 10 = 40° ; 5x = 5 * 10 = 50°
