Question

1) a circus artist is climbing a 20 m long rope,which is tightly stretched and tied from the top of a vertical pole to the ground. find the height of the pole if the angle made by the rope with the ground level is 30 degree

Answer 1

so the length of the vertical pole is 10m

Answer 2

_/\_Hello mate__here is your answer--

=============================

Solution:

We have 20 m rope AC here as shown in the figure above.

We want to find height of the pole which is AB.

X/20=sin30°

⇒X/20=1/2 ( sin 30° = 1/2 )

⇒X=20×1/2=10 m

Therefore, Height of the pole is 10 m.

I hope, this will help you.☺

Thank you______❤
