Find the measure of each equalateral triangle if AB=2x, BC=x+7, CA=4x-14

X = 7

AB = 14

BC = 14

CA = 14

Step-by-step explanation:

This is an equilateral triangle so you can set the lengths equal to each other in order to find X.

2x=x+7

-x - x

x=7

you can do this with any combination of the lengths and you will always get 7

Now you plug in 7 for x

Original: 2x

Plug in 7: 2*7

You get 14

Since this is after all, an equilateral triangle all lengths are equal so all lengths are 14.
