Help help help!!!!!!!!!!!!!!!!!

Answer 1

91°

Explanation:

Angle 2 and 3 are supplementary angles (they add up to 180).

Lets write an equation and solve for x:

`5x+14+7x-14=180\\12x=180\\x=(180)/(12)\\x=15`

Also, Angle 1 and Angle 3 are vertical angles and they are EQUAL.

So angle 1 is also 7x - 14. And x = 15 so Angle 1 is:

Angle 1 = 7x - 14 = 7(15) - 14 = 91
