-4x + 15 > 59
-4x > 44
x < -11 - switch the inequality when dividing or multiplying by a negative number
Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)
