Since they are both degrees of an angle they would be equal:
3x+80 = 7x-40
80 = 4x-40
120 = 4x
x = 120/4 = 30 degrees
Step-by-step explanation:
The Symmetric Property states that for all real numbers x and y , if x=y , then y=x . Transitive Property. The Transitive Property states that for all real numbers x ,y, and z, if x=y and y=z , then x=z .
Slope is -12 and y-intercept is 3
