If m( angle 1) = 4x + 10 and m( angle 7) = 6x + 4, what are the measures of angles 1 and 7?

I'm not sure how to show my work. Angle 1 and angle 7 are congruent alternate exterior angles

1 answer

If they are "congruent" then they must be equal
so solve

6x+4 = 4x + 10 for x, then sub it back into the angle expressions
