Question

A circus artist is climbing 20 m long rope and tied from the top of a vertical pole on the ground. Find the height of the pole , if the angle made by the rope with the ground level is 30°​

Answer 1

Answer:

it will be 30 ℅ of 20m

Step-by-step explanation:

30/100 * 20

= 3*20/10

= 60/10

= 6metre

hope it helps

Answer 2

Let AB be the vertical pole and AC be 20 m long rope tied to point C .

In right triangle ABC ,

${ sin30° = \frac {AB}{AC}}$

${ \implies \frac{1}{2} = \frac {AB}{20}}$

${\implies AB = \frac {20}{2}}$

${\implies AB = 10}$

The height of the pole is 10 m .
