The smallest angle in a triangle is 1 5 15 as large as the largest angle. 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

Let x be the smallest angle. Then we have 5x + x + 2x = 180.

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.
