The leg of a right triangle is 4 units and the hypotenuse is 9 units. What is the length, in units, of the other leg of the triangle?

A. Square root 97 units

B. 97 units

C. Square root 65 units

D. 65 units

Length of the other leg of the triangle is √65 units

Step-by-step explanation:

Step 1: Find the length of the other leg using Pythagoras Theorem.

Hypotenuse² = One side² + Other side²

9² = 4² + Other leg²

Length of the other leg² = 81 - 16 = 65

⇒ Length of the other leg of the triangle = √65
