A square is put together by two triangles. The hypotenuse is 11 cm and width of 8 cm. find the height of triangle?
Aleks [24]
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
