Question

HELP QUICK help find the value of x and the measure of each angle

Answer 1

Answer: x=30 A=102 B=78

Step-by-step explanation:

These are linear pairs so they add up to 180.

Your equation is: 3x+12+2x+18=180

5x+30=180

x=30

Plug x into the equations to find their values.

3(30)+12=102

2(30)+18=78

Answer 2

A = 102° B = 78°

Explanation:

(3x + 12°) + (2x + 18°) = 180°

5x = 180° - 12° - 18°

5x = 150|:5

x = 30°
