= $\frac{(5.35)^3+(3.65)^3}{(53.5)^2+(36.5)^2-53.5 \times 36.5}$
= $\frac{(5.35+3.65)((5.35)^2+(3.65)^2-5.35 \times 3.65)}{100\times[(5.35)^2+(3.65)^2-5.35 \times 3.65]}$
= $\frac{5.35+3.65}{100}$
= $\frac{9}{100}$
= 0.09
Hence, the correct answer is 0.09.

Question : A kite is flying at a height of 50 metres. If the length of the string is 100 metres, then the inclination of the string to the horizontal ground in degree measure is:

Option 1: 90°

Option 2: 60°

Option 3: 45°

Option 4: 30°

Team Careers360 25th Jan, 2024

Correct Answer: 30°


Solution :
Given: A kite is flying at a height of 50 metres.
The length of the string is 100 metres.
We know that $\sin\theta=\frac{\text{perpendicular}}{\text{hypotenuse}}$
$\text{Hypotenuse}$ = 100 m
$\text{Perpendicular}$ = 50 m
⇒ $\sin\theta=\frac{50}{100}$
⇒ $\sin\theta=\frac{1}{2}$
⇒ $\sin\theta=\sin30°$
⇒ $\theta=30°$
Hence, the correct answer is 30°.
