Sure, there's such a thing as an isosceles right triangle. It's what you get when you draw the diagonal of a square. It has one right angle (of course) and two 45 degree angles. It's the shape that vexed the Pythagoreans.
The first thing to do is to substitute the b and c. The equation will look like this, a+3a+5a=180. Then you must add the a's all together because they are all the same, remember that "a" represents 1. It will look like this in plain 1 + 3 + 5. Then the equation is 9a = 180. to get the "a" you must eliminate or divide the equation into 9 and it will look like this, <u>9a</u> = <u>180</u> Then the answer will be a = 20
