Answer 2

Answer:

1) 102

2) x = 31°; y = 6

3) m = 28°, n = 31°

4) x = 79°

Step-by-step explanation:

1) Angle ABD = 180 - 2(69) = 42

Angle DBC = 180/3 = 60

Angle ABC = 42 + 60 = 102

2) Angle ABC = 180 - 2(59) = 62

x = 62/2

x = 31°

ABD and CBD are congruent triangles so y = 6

3) 118 = m + 90

Exterior angle = sum of interior angles

m = 118 - 90 = 28°

n = (180-118)/2 = 31°

4) x = (180-22)/2 = 79°
