Question

LAST OF MY GEOMETRY PLZ HELP

Answer 1

Explanation:

14) 2x - 10 = 80 {alternate interior angles are equal}

2x = 80 + 10

2x = 90

x = 90/2

x = 45°

15) 3x + 120 = 180 { co interior angles are supplementary}

3x = 180 - 120

3x = 60

x = 60/3

x = 20°

16) 3x + 15 = 135 {corresponding angles are equal}

3x = 165 - 15

3x = 150

x = 150/3

x = 50°
