Question

How long is a string reaching from the top of a 13-ft pole to a point on the 3 points ground that is 7 ft from the base of the pole?

Answer 1

14.8

Explanation:

We use the Pythagoras theorem because the string and the pole are making a right angle triangle

7^2+13^2=c^2

49+169=c^2

218=c^2

14.8=c

Answer 2

14.76 ft

Explanation:

L²= 13² + 7²

L² = 169 + 49 = 218

L = √218 = 14.76 ft
