Question

A building is 200 feet high. One end of a wire is attached to the top of the building.

The other end is attached to the group 150 feet away from the base of the building. How
long is the wire?

Answer 1

250 feet

Explanation:

If you draw out this situation, you would get a right triangle with a height of 200 (feet) and a base of 150 (feet). The wire is the missing length, or the 'hypotenuse' of this right triangle. You use the pythagoras thingie, and the formula is a^2 + b^2 = c^2.

a= 200

b= 150

c= ?

40,000 + 22,500 = c^2

62,500 = c^2

c = √62,500

∴ c = 250
