Question

Find the third side in simplest radical form:

Answer 1

`√(130)`

Explanation:

since the triangle is a right triangle

we can use the Pythagorean theorem to find the hypotenuse

• let a=7, b=9, c= ?
• c² = 7² + 9²
• c =
  `√(130)`

Answer 2

• √130

Explanation:

Using Pythagorean theorem to find the third side

• √9²+7² =
• √81+49=
• √130
