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
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
