Question

What is the answer to this question

Answer 1

Firstly,we need to find the sum of opposite angle of 4x,which is 45°+15°=60°

since the right opposite angles have a same degree,the equation would be:

4x=60°
x=60°/4
x=15°

Thus,the answer is 15°

Hope it helps!

Answer 2

vertical angles are equal

4x = 45 + 15
4x = 60
x = 60/4
x = 15
