Answer:

A = 41

B = 31

Explanation:

angles in a triangle add up to 180 degrees

the three angles in this triangle: 108, x+5, x-5

added up, we get

108 + (x+5) + (x - 5) = 180

= 108 + 2x + 5 - 5

= 108 + 2x

subtract 108 from both sides to isolate the variable and its coefficient

72 = 2x

divide both sides by 2 to solve for x

x = 36

A = x + 5 = 36 + 5 = 41

B = x - 5 = 36 - 5 = 31
