PLEASE HELP ME WITH THIS

figure 1). x = 36 2). x = 123

Explanation:
Figure 1:
Angle x = angle 1

And angle 4 = 4x

Angle 4 + angle 1 = 180
4x + x = 180
5x = 180
x = 36

Figure 2:
Angle 1 = 68 degree
Angle 2 = 55 degree

Find angle 3:
180 - (68 + 55)
= 180 - 123
= 57 degree

But angle 3 = angle 4 = 57 degree

But: angle 4 + x = 180
57 + x = 180
x = 180 - 57
x = 123
