Answer:
70 degrees
Step-by-step explanation:
Well the total measure of a triangle is 180 degrees.
which means all angles add up to 180 degrees
there are 3 angles in a triangle
one is 50 degrees and the other is 60 degrees. the third equals 180-the two other angles.
180-(50+60)=70 degrees
this works because 50+60+70=180
