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°
