Question

a circus artist is climbing a 20 metre long rope which is tightly stretched and tired from the top of a vertical pole to the ground find the height of the pole if the angle made by the rope with ground level is 30 degree​

Answer 1

17.32 is the answer to thisquestion

Answer 2

$\huge\tt\underline\red{GIVEN:-}$

$\large\sf\red{AB=light\:of\:pole}$

$\large\sf\red{AC=rope}$

$\large\sf\pink{In\:∆ABC,}$

$\large\sf\pink{Sin\:30°=\frac{AB}{AC}=\frac{AB}{20}}$

$\large\sf\pink{So,\frac{1}{2}=\frac{AB}{20}}$

$\large\sf\pink{AB=10m}$

$\therefore$$\large\tt\underline\purple{Height\:of\:pole=10m}$
