Find the measures of all angles formed by line a parallel to line b with transversal m, if:

one angle is 25° bigger than another

3 answers

all the angles are either congruent or supplementary.
So, if one angle is x, and the other angle is x+25, then
x + x+25 = 180
and now you can finish it off.
Use the given information to find the measures of all angles formed by parallel lines a and b, and transversal m.
x+x+25=180
2x+25=180
2x=180-25
2x=155
x=77.5
x=77.5, add 25 and you get the second number

Answer= 77.5, 102.5
