Distribute 
to every term inside the parentheses.
Simplify with multiplication.
You can't simplify further by adding, so leave the answer as-is.
Use Pythagorean theorem
a^2 + b^2 = c^2
Other words, lengths of the shortest sides squared are equal to the longest squared
a^2 + 9^2 = 15^2
a^2 + 81 = 225
a^2 = 144
a = squareroot of 144
a = 12
Solution: a = 12
136 + x = 189
-136 -136
x = 53
