Question

Two poles, 18m high and 13 m high, stand upright in a playground. If their bases are 12m apart, find the distance between their tops

Answer 1

Answer:

13

Step by step epplination:

If we practically do this we find trepazium

If we cut side of pole of 18m and made two pole side epual to make we have to subtract 18-13 we find 5 now we have a triangle. Let name the triangle ABC now ab=5, bc=12 now we have to find AC. Now we use pythagores theorm.

(H)

${h}^{2} = {p}^{2} + {b}^{2}$

${h}^{2} = {5}^{2} + {12}^{2}$

${h}^{2} = 25 + 144$

${h}^{2} = 169$

$h = \sqrt{169}$

H = 13

So the distance between their top is 13
