Question

The hypotenuse of a right triangle has a length of 14 units and a side that is 9 units long. Which equation can be used to find the length of the remaining side?

Answer 1

10.7 units

Explanation:

Well this is actually pretty simple.

You have to use the Pythagorean Theorum formula which is
`a^2+b^2=c^2` and in this case we have a and c.

So c is 14 and a is 9 so we can plug those numbers in.

`(9)^2+b^2=(14)^2`.

So 9 squared is 81 and 14 squared is 196.

So to get b by itself we have to subtract 81 by 196 which is 115.

Now we have to find the square root of 115 and b which is b and about 10.7 units.

So The length of the remaining side is 10.7 units.

Answer 2

Explanation:

Pitagora theorem is 14^2=9^2+x^2

-9^2 -9^2

so the equation is

x^2=14^2-9^2
