You make an equation knowing that the angles add up to 180.

80+5x=180---> 5x=100----> x=20

Answer:

x = 20 degrees

Step-by-step explanation:

All three angles added together form a straight line.  A straight line is 180 degrees

3x+ 80 + 2x = 180

Combine like terms

5x+80 = 180

Subtract 80 from each side

5x+80-80 = 180-80

5x= 100

Divide each side by 5

5x/5 = 100/5

x = 20
