Answer 1

Answer:

(5). x = 10; (6). x = 55; (7). x = 20; (8). x = 23, y = 43; (9). m = 42.25; (10). x = 5.5.

Step-by-step explanation:

5). (5x + 3)° + (2x + 17)° = 90°

5x + 3 + 2x + 17 = 90

7x = 70

x = 10

6). (2x)° = 110°

2x = 110

x = 55

7). (3x + 3)° + (x + 7)° = 90°

3x + 3 + x + 7 = 90

4x = 80

x = 20

8). (3y - 12)° + 63° = 180°

3y - 12 + 63 = 180

3y = 129

y = 43

(5x + 2)° + 63° = 180°

5x + 2 + 63 = 180

5x = 115

x = 23

9). (2m - 3)° + (m + 8)° + (m + 6)° = 180°

2m - 3 + m + 8 + m + 6 = 180

4m + 11 = 180

4m = 169

m = 42.25

10). 5x + 2 = 3x + 13

2x = 11

x = 5.5
