Answer:

A. x = 50

Step-by-step explanation:

x° + (x + 10)° + (x + 20)° = 180° (sum of interior angles of a triangle)

Solve for x

x + x + 10 + x + 20 = 180

Add like terms

x + x + x + 10 + 20 = 180

3x + 30 = 180

Subtract 30 from each side

3x + 30 - 30 = 180 - 30

3x = 150

Divide both sides by 3

3x/3 = 150/3

x = 50
