Answer:
The answer to your question is below
Step-by-step explanation:
1)
Process
1.- Find z
z = 107° because they are vertical angles
2.- Find x
5x - 7 + 107 = 180 Because they are supplementary angles
5x = 180 + 7 - 107
5x = 80
x = 80/5
x = 16
2)
The sum of the internal angles in a triangle equals 180
65 + 50 + x = 180
x = 180 - 65 - 50
x = 65°
