Find the value of x.
A) 71
B) 72
C) 73
D) 75

Answer:
The answer is c) 73
Step-by-step explanation:
The angle 146 and (-39 + x) lie on the same line, so that means their sum is 180 degrees because a straight line has 180 degrees.
180 = 149 - 39 + x
180 = 107 + x
180 - 107 = x
73 = x
Answer:
73
Step-by-step explanation:
The two angles form a straight line and a straight line is 180 degrees
-39+x + 146 = 180
Combine like terms
107 +x = 180
Subtract 107 from each side
107+x-107 = 180-107
x =73
