Question

pls answer this math ques

Answer 1

As shown in the picture (not to scale), the poles form a right triangle, with the two leg sides 36 m and 15 m.

Using the Pythagorean Theorem (a^2 + b^2 = c^2), we can solve for x.

36^2 + 15^2 = x^2

1296 + 225 = x^2

1521 = x^2

x = 39 m

Also, if you have a knowledge of Pythagorean Triples, you could discern that his triangle contained multiples of the 5, 12, 13 triangle.
