Question

The equation a2 + b2 = ca represents the relationship between the three sides of a right triangle.

Hal leans a ladder that is 26 feet long against the side of a building. The base of the ladder is 10 feet from the side of the building.
How high up the side of the building is the top of the ladder?
A 24 feet
B 22 feet
C 28 feet
D 16 feet

Answer 1

Explanation:

I think you mean a² + b² = c², not ca.

a = 10, c = 26

b² = c² - a² = 26² - 10² = 576

b = √576 = 24 ft
