Answer 2

Answer:

2.

a. 50°

b. 130°

c. 75°

d. 40°

e. 30

Step-by-step explanation:

We will use angle sum property of triangle here. [ Sum of all angles of triangles is 180°.]

a) x + 60 + 70 = 180

x + 130 = 180

x = 180 - 130

x = 50°

b) x + 30 + 20 = 180

x +50 = 180

x = 180-50

x = 130 °

c) 30 +75 + x = 180

105 + x = 180

x = 180 - 105

x = 75°

d) x + x + 100 = 180

2x = 180 -100

2x = 80

x = 40°

e) 3x + 2x + x = 180

6x = 180

x = 30°
