Answer:

a=17

Step-by-step explanation:

This triangle has identical sides on each, which means it is an equilateral triangle. When a triangle has equilateral sides, it also has equilateral angles.

A triangle has 180 degrees, so lets' divide by three since there are three angles. The answer is 60, so every angle in this picture is 60 degrees.

Now, we need to find a. We know that this angle is equal to 60 degrees, so let's equal it with the small equation.

4a-8=60           Let's get rid of the 8 by adding 8 to both sides.

4a=68               Isolate the variable by dividing four to both sides.

a=17

Your final answer is a=17.
