Question

Suppose you are making a sail in the shape of a right triangle for a sailboat. The length of the longest side of the sail is 65 ft. The sail is to be 63 ft high. What is the length, in feet, of the third side of the sail?

Answer 1

Answer:

in right angled triangle ABC

hypotenuse [h]=65ft

base[b]=xft

height[p]=63ft

by using Pythagoras law

h²=p²+b²

65²=63²+x²

x²=65²-63²

x=√256

x=16feet

so the third side of the sail is 16ft.
