Question

A right triangle has of length 3, 4, and x. find the x.

Answer 1

1) x = 5

2) x = √7

Explanation:

1) Using Pythagoras theorem, we can find x.

Given:

• x = hypotenuse

=> x² = 3² + 4²

=> x² = 9 + 16

=> x² = 25

=> √x² = √25

=> x = 5

2) Using Pythagoras theorem, we can find x.

Given:

• x = The leg of the right triangle.

=> 4² = x² + 3²

=> 16 = x² + 9

=> x² = 7

=> √x² = √7

=> x = √7

Hoped this helped.
