B.)140
C.)5
D.)1

Answer 1

C is the answer
(5x+15)=(6x-10)
-6x. -6x
(-x+15)=-10
-15. -15
-x=-10

Answer 2

25 = x

Explanation:

The angles are vertical angles and vertical angles are equal

5x+15 = 6x -10

Subtract 5x from each side

5x-5x+15 = 6x-5x -10

15 = x - 10

Add 10 to each side

15+10 = x-10+10

25 = x
