Question

Please help me on my angles assignment I'm stumped on this last question 20 point grade 6

Answer 1

x = 77.5

Explanation:

x and x + 25 are a linear pair and sum to 180° , that is

x + x + 25 = 180

2x + 25 = 180 ( subtract 25 from both sides )

2x = 155 ( divide both sides by 2 )

x = 77.5
