Question

Solve for x in the diagram below

Answer 1

x = 15

Explanation:

4x is congruent to 45 + 15

4x = 45 + 15

simplify 4x = 60

divide both sides by 4 x = 15

Answer 2

x = 15

Explanation:

4x is the vertical angle to the sum of 45 and 15 so they are equal

4x = (45+15)

4x = 60

Divide each side by 4

4x/4 = 60/4

x = 15
