Question

A. Solve for x. B. Is the triangle equilateral?​

Answer 1

x=8

No it’s not an equilateral

Explanation:

Since side AB is about the same length as BC we can set them equal to each other

x-1=7

+1 +1

x=8

This is not an equilateral because if you fill in X for the third side you will get 5

8-3=5
