Answer 1

Step-by-step explanation: 4x - 4 + 60 = 90

+4 -66. -66

Answer 2

1) 145°

2) 20°

3) x = 7 ; measurement of the missing angle = 24

Explanation:

1) supplement = 180°, 180 - 35 = 145

2) complment = 90° , 90 - 70 = 20

3) the figure is a right angle so the measurement is 90°

66 + (4x-4) = 90

62 + 4x = 90

4x = 28

x = 7

4(7) - 4

28 - 4

= 24
