A right triangle has a leg length of square root of 7 and a hypotenuse length of 4. Determine the length of the other leg of the right triangle.

square root of 57
square root of 49
8
3



Answer :

The length of the other leg of the right angles triangle is 3. Option D

How to determine the length of the side

The Pythagorean theorem states that the square of the hypotenuse side is equal to the square of the other two sides in a right angled triangle.

We have;

a² = b² + c²

Where;

  • a is the hypotenuse
  • b is the opposite side
  • c is the adjacent side

Now, substitute the values

4² = (√7)² + c²

Find the square values

16 = 7 + c ²

collect like terms

c² = 9

Find the square root of both sides

c = 3

Hence, the value is 3
