Please help! The second angle in a triangle is twice as large as the first. The third angle is three times as large as the first. Find the angle measurements



Answer :

All angles of a triangle must be equal to 180 degrees. From that:
x- our basic angle
2*x- second angle
3*x- third angle
so:
x+2x+3x=180
6x=180
x=180/6
x=30 degrees
second angle is 60, and third is 90
Checking
30+60+90=180
