Question

What is the length of the ladder? its 6ft from the house at the bottom and touches the wall 14ft up at the top

Answer 1

Exact: 2√58 ft

Approximate: 15.2 ft

Explanation:

The ladder, the ground, and the wall form a right triangle.

a² + b² = c²

6² + 14² = c²

c² = 232

c = √232

c = √(4 × 58)

c = 2√58 = 15.2
