Question

A rope goes from one building to another. The distance between the buildings is 10m, and the rope is tied at each building at a point 8m and 4m from the ground. Find the length of the rope.

Answer 1

Answer:

Step-by-step explanation:

Think of it as a triangle.

They give you the length of the bottom side and the location of the tops of the buildings.

You need to find the hypotenuse ( the longest side or the length of the rope)

Use the pythagorean theorem

$a^{2} + b^{2} = c^{2}$

10 ^2 + 4^2= c^2

100 + 16 = c^2

116 = c^2

c is about 10.77
