Question

Ive been at this for three hours bro please help me

Answer 1

`\\ \rm\Rrightarrow 3x+3+84=180`

`\\ \rm\Rrightarrow 3x+87=180`

`\\ \rm\Rrightarrow 3x=93`

`\\ \rm\Rrightarrow x=31`

Answer 2

x = 31 degrees

Explanation:

Transversals! You are given that line m is parallel to line n. Therefore, the angle above 84 degrees is equal to 96 degrees.

Opposite angles are congruent, so you set 3x+3=96

Solve for x.

Another way to think of this is that a straight angle is 180 degrees. That means both angles added together must equal to 180 degrees. 3x+3+84=180

Solve for x
