Example Question #2 : How To Find The Length Of The Side Of A Right Triangle
The hypotenuse of a right triangle is 26 in and one leg is 10 in. What is the sum of the two shortest sides?
We use the Pythagorean Theorem so the problem to solve becomes where = unknown leg length
So and
The sum of the two legs becomes

Example Question #3 : How To Find The Length Of The Side Of A Right Triangle
Find the length of the unknown side, , of the right triangle below.
We need to use the Pythagorean Theorem, which says that .
Since we need to find the length of 'a', we can just solve for 'a'.
In our case, c = 12 and b = 9.
Thus, .
Example Question #2 : How To Find The Length Of The Side Of A Right Triangle
Find the missing leg of the right triangle when one of the legs is and the hypotenuse is .
In order to find the missing side of a right triangle you must use one of two things:
1. Pythagorean Theorem
2. Trigonometry.
Since we only know what the side lengths are we must use the Pythagorean Theorem.
a=4, b=x, and c=5
So the missing side length is 3
Example Question #1 : How To Find The Length Of The Side Of A Right Triangle
Given that the hypotenuse of a right triangle is and one side is , find the other side length.
To find the length of the missing side, you can either use the pythagorean theorm or realize this is a case of a special right triangle with sides .
Thus, the other side length is .
Example Question #2 : How To Find The Length Of The Side Of A Right Triangle
Find the length of the missing side.
Recall the Pythagorean Theorem for a right triangle:
Since the missing side corresponds to side , rewrite the Pythagorean Theorem and solve for .
Now, plug in values of and into a calculator to find the length of side . Round to decimal places.
Example Question #3 : How To Find The Length Of The Side Of A Right Triangle
Find the length of the missing side.
Recall the Pythagorean Theorem for a right triangle:
Since the missing side corresponds to side , rewrite the Pythagorean Theorem and solve for .
Now, plug in values of and into a calculator to find the length of side . Round to decimal places.
