A 15-foot ladder is leaning against a building with the base of the ladder 4 feet from the building. How high on the building the top of the ladder will reach?

14.46ft

Step-by-step explanation:

this would be solved using Pythagoras

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

15^2 - 4^2

225 - 16 = 209

the square root = 14.46

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
