Question

If m = 80° and m = 30°, then m 3 =

Answer 1

I’m going to assume this is about a triangle and the measurement of angle 1 is 80 degrees and the measurement of angle 2 is 30 degrees
If you want to find the measurement of the third angle you just have to subtract everything from 180
180-80-30=70
The measurement of the last angle is 70degrees
