Answer:
x= 85 is the answer. ( because exterior angle of a triangle is equal to 2 non adjacent interior angle of a triangle..)
x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7
The standard form: ax + by = c
and your equation is: -2x + 3y = - 5 (Yes this is written in standard form)
