Question 262894
Hello, 
This will take a couple steps to solve. First, let's find the length of the base of the triangle with the following formula: A^2+B^2=C^2 
"A" will represent one leg of the triangle and "C" will be the diagonal. Plug in the numbers:
8^2+B^2=15^2 Do the calculations:
64+B^2=225Subtract 64 from both sides to get:
B^2=161 Now square root both sides to result in:
B=12.69 (Rounded off)
Now we take the area of a Triangle which is:
Area=1/2Base*height
Plug in the numbers.
A=1/2(12.69)(8) Do the calculations. 
A=50.76 square units. 
Make sense?
