Subtract the 2 on both sides to get -4x=-5x+7, then add -5 on both sides and get 1x=7 then divide 1 on both side to get x=7
X is a vertical angle to the angle marked as 100 degrees.
Vertical angles are the same so x = 100 degrees
Answer: 100 degrees
Answer:
B- 125
Step-by-step explanation:
c + a = 400
a = 400 - c
5c + 8a = 2825
5c + 8(400 - c) = 2825
5c + 3200 - 8c = 2825
3c = 375
c = 125
