The Length Of The Sides Of A Triangle Are In The Ratio 8 15 17 Find The Len

Help as soon as possible would be greatly appreciated.

Let’s name your triangle sides a, b and c. Now if we translate your problem we can say that ratio of a:b:c is the same as 8:15:17 or we can write:

a/8=b/15=c/17

Since these ratio are the same, let cal this ratio k, so

a/8=b/15=c/17=k

From here we can write:

a=8k

b=15k

c=17k (by cross multiplication)

Now let’s use last given information perimeter is 136

a+b+c=136

8k+15k+17k=136

40k=136

k=3.4

Now, using ratio k you can find each side:

a=8×3.4=27.2

b=15×3.4=51

c=17×3.4=57.8
