Answer:
a. Andrea is incorrect
b. By solving for x, we find that x does not equal 8, but it is equal to 7.
Step-by-step explanation:
8+4=2(x-1)
8+4=2x-2
12=2x-2
14=2x
x=7
Answer:
-6-3
Step-by-step explanation:
Answer:
7+12+2=21
Step-by-step explanation:
Answer:
Step-by-step explanation:
Vertical angles are equal. Thus, 3x + 14 = 5x, and 14 = 2x.
Then x must be 7.
The first angle, 3x + 14, is 3(7) + 14, or 35.
The second, 5x, is 5(7) = 35
As expected, the two angles are equal.
