The third Ouch! this hurts! The smallest angle in a triangle is 1/5 as large as the largest angle. The third angle is twice the smallest angle. Find the three angles. trying to get rid of fraction before solving if possible. As fractions really hurt me. so i am guessing I first need to go 5/5 *1/5 Yet with out being able to figure out formula for the problem not sure how I would go about doing this? Thanks for your help. These make my head hurt, and make me feel physicaly ill.

why deal with the fractions? if one quantity is 1/5 another, then the latter is 5 times the initial quantity ...

let the smallest angle = x

largest angle = 5x

third angle = 2x

sum of all three angles is 180 degrees

Oh sorry, I was thinking that 1/5 of the other, meant i had to find out what was the other 4/5 but 1/5 does not or 1/2 for example mean fractions are involved.

You have saved me again

 Tags angle, large, largest, smallest, triangle

,

### 3 times smallest and other is five times the smallest find the angle
