You can put this solution on YOUR website!
Let x = measure of each base angle (there are 2 equal base angles!)

Recall that the sum of the angles of a triangle is 180 degrees.
x+x+ 48=180
2x+48=180
2x=132
x=66 degrees

Check 66+66 + 48 = 180

On my website (click on my tutor name "rapaljer" anywhere in algebra.com}, I have several sections on Geometric topics. Look for "Topics from Geometry." There are several pages here that may apply and provide additional resources for you.
