Answer:
You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.
Answer:
The sum is 
Step-by-step explanation:
The given expression is

These are all quadratic trinomials, so we split each of the middle terms to obtain,

We factor to obtain,

We factor further to obtain,

We cancel out the common factors to get,

The least common denominator is
.
We collect LCD to get

We now expand to get,

We simplify to get,

We simplify further to get,
