Answer:
50°
Step-by-step explanation:
The missing angle, <C, is an angle on a straight line with the two other angles who measures are 65% each.
Therefore:
65 + 65 + C = 180° (angles on a straight line)
130 + C = 180
Subtract 130 from both sides
130 + C - 130 = 180 - 130
C = 50°
Y = 15
180 = 142 + 2y + 8
180 = 150 + 2y
30 = 2y
y = 15
x = 30.5
142 = 4x + 20
122 = 4x
x = 30.5
