You can use the pythagorean theorem. Make sure that you put the measurements in the right places though. Since 11 is the measure of the hypotenuse, 11 has to be c. When you plug in the information that you have, it should look like this: 8^2 + b^2 = 11^2
Square 8 and 11. 64 + b^2 = 121
Subtract 64 from 121 121 - 64 = 57
The new equation is: b^2 = 57
Now take the square root of both sides to get b by itself. b = about 7.5
Answer: The height of the triangle is 7.5

Ok? what's the rest, u can't solve unless there's a question like : how many hours does he have to work in order to go on vacation, I'm sorry but u make no sense
