Question

Two poles of height 6 m and 11 m stand vertically upright on a plane ground. If the distance between their foot is 12 m, the distance between their tops is option a)14 m b)12m c)13 d)11​

Answer 1

Answer:

Given: Two poles AB=11 m and CD=6m

Distance between both poles BD=12 m

Then, create a line segment CE parallel to line BD

So, AE=AB−CD=11−5=6 m

In right angled △AEC,

(AC)² =(AE)²+ (EC)²

      = 5² + 12²= 169

⇒AC=13 cm

Therefore, the distance between their tops is 13 cm.

Hence, the correct option is (c).

Please mark me the brainliest.

Answer 2

Answer

c)13 is the correct answer

Step by step explaination

AB is the pole with height 11m, distance between their foot i.e. DB is 12 m. Let us assume a point E on the pole AB which is 6m from the base of AB. Thus, the distance between their tops is 13m. Hence correct answer is C)13
