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° (see Fig. 9.11).​

Answer 1

Answer:

Let AB be the vertical pole and CA be the rope. Then,

∠ACB=30 and AC=20 m

In right △ ABC,

sin30   =  AC /AB

1/2=AB/20

AB=10m

Therefore, the height of the pole is 10 m.

Answer 2

Answer:

26 meter is the answer

Step-by-step explanation:

because if the rope is 20 m long and at the 30⁰ that's why the length will be 26 m
