Question

What is the value of x?



13.6

68

84

9.09

Answer 1

x=13.6

Explanation:

These are vertical angles, so they are equal

8x+16 = 3x+84

Subtract 3x from each side

8x-3x+16 = 3x-3x+84

5x+16 = 84

Subtract 16 from each side

5x+16-16 = 84-16

5x = 68

Divide by 5

5x/5 =68/5

x = 13.6
