Answer:
60
Step-by-step explanation:
Total degree of triangle interior angles is 180
So x+2x+3x=180
6x=180
x=30
Measurement of angle C is 2x which is 60 degree
Maybe using a protractor might help. But know that a straight angle equals 180. I don't really understand it. But use the <span>Pythagorean Theorem so a^2+B^2=c^2</span>
