Answer:
C. x=42
Explanation:
First find the measurement of missing angles. 126+16=142
180-142=38
Now, 16, 3x and 38 should add up to 180 because it is a line.
16+38+3x=180
54+3x=180
Solve for x.
3x=126
3 = 3
x=42. Hope this helps.
148
180 is the whole thing and if the inner of one is 16 then the other one is also 16 so u add this and subtract 180-32=148
(16+16=32)
