Hello!
We know that x is 9
6(9) +5 = 59
Angles 2 + 1 are supplementary to the angle we just figured out
180 - 59 = m<1 + m<2
121 = m<1 + m<2
We know that angle 1 is 48° because it is same side alternate angles from the 48° angle
121 = 48 + m<2
Subtract 48 from both sides
73 = m<2
The answer is 73°
Hope this helps!
