Answer pls, I don't understand

I think its 136

Step-by-step explanation:

A line must equal 180° so the equation would be 180=4x-48 then you just solve for x and put and put the number where ever xbox goes and subtract 180

124

Step-by-step 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

we need the options

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137
