Answer:

x = 56

Step-by-step explanation:

The sum of a triangle add up to 180, so add all of the angles in the triangle and equate to 180

x + x + 7 + x + 5 = 180

collect like terms to simplify

3x + 12 = 180

subtract 12 on both sides

3x = 180 - 12

3x = 168

divide 3 on both sides

x = 168 ÷ 3

x = 56
