Question

Can someone help me with this questions please?

Answer 1

2. x = 15 deg; Δ=45 deg

Answer 2

Since supplementary angles equal 180. (2x+15) = 45, which can be found by subtracting 135 from 180. This means that x = 15. And since angle 1 corresponds to the previous angle, we can deduce that angle 1 = 45.
