Answer:
124
Explanation:
Since the angles with equations are vertical angles we can set them equal and find x.
x+30=4x-48
solve for x
30=3x-48
78=3x
26=x
Plug 26 into one of the equations.
x+30
26+30
56
Angle 1 and this angle have a sum equal to 180. Subtract this angle from 180.
180-56
124
Angle 1 = 124
