Question

What is the value of x?

Answer 1

16

Explanation:

As the angles are vertically opposite

7x + 8 = 8x - 8

x = 16

Answer 2

Explanation:

`(8x - 8) \degree \: and \: (7x + 8)\degree \: are \: \\ vertically \: opposite \: angles. \\ vertically \: opposite \: angles \: are \: \\ congruent \\ \therefore \: (8x - 8) \degree \: = \: (7x + 8)\degree \\ \therefore \: 8x - 7x = 8 + 8 \\ \huge \pink{ \boxed{\therefore \: x = 16\degree}}`
