Question

The leg of a right triangle is 3 units and the hypotenuse is 11 units. What is the length, in units, of the other leg of the triangle? HURRY PLEASE!!!

a
112 units

b
square root 112 units

c
130 units

d
square root 130 units

Answer 1

The correct option is (b) square root 112 units

Explanation:

By using Pythagoras theorem,

• a² + b² = c²

where a & b = legs of triangle and c = hypotenuse

Hence:

• 3² + b² = 11²
• 9 + b² = 121
• b² = 121 - 9
• b² = 112
• b = √112
