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
***** Note: I rounded the answer ********************************************
A year has 12 months so 1 month = 1/12 year. t = 3 months = 3/12 year = 1/4 year
14) You would put 14 over unknown is poportional to 40 over 100. Then multiply 14 by 100 then divide it by 40 to receive 35.
