Answer:
The answer is x=13
Step-by-step explanation:
We know that in total the triangle is 180 degrees, we also know that each side is congruent. Using this thought process, we divide 180 by 3, one for each side. This leaves us with 60 Degrees per angle. We can now insert 60 as the answer to the equation (4x+8=60) We then subtract 8 from 60, leaving us with 52. Now we can divide 52 by 4, leaving us with 13.
