Question 521926: my homework question is about triangles, and finding the degree of each angle, ive done them all but am confused about the ones like these, please help me figure out how to evaluate them.
it says: m<1(angle 1)= x+30; m<2= x-22; m<3= 2x-7; find x, and the measure of each angle.

sum of all angles of triangle = 180 deg

x+30+ x-22+ 2x-7=180
4x+1=180
4x=179
x=44.75
m1= 74.75
m2=22.75
m3=82.50
Total = 180
