Answer:B
Step-by-step explanation:
Answer:
1. Since the angles on the both sides are the same
5x = 100
x = 20
The mistake is that it is absolutely unnecessary to use 180.
2. It is a right angle, which means it would be 90 degrees instead of 180.
3x + 39 = 90
3x + 39 - 39 = 90 - 39
3x = 51
3x = 17
3. The process is wrong
It should be
6x + 2x + 8 = 180
8x + 8 = 180
8x = 172
x = 21.5
