SOLUTION: a second angle of a triangle is twice the smallest angle. The largest an is 20 degrees more than the second angle. Find the three angles of the triangle.

Question 375327: a second angle of a triangle is twice the smallest angle. The largest an is 20 degrees more than the second angle. Find the three angles of the triangle.

Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
let smallest angle be x
second angle = 2x
largest angle = 2x+20
..
x+2x+2x+20=180
5x+20=180
-20
5x=180-20
5x=160
/5
x= 160/5
x=32 -- smallest angle
..
second angle = 2x = 2*32= 64
third angle = 2x+20 = 2*32+20=84
...
CHECK
32+64+84=180
