Option 3: 550

Option 4: 500

Team Careers360 15th Jan, 2024

Correct Answer: 600


Solution : Distance = 200 m
Speed of thief = 6 km/h = $6\times{\frac{5}{18}}$ = $\frac{15}{9}$ m/s
Speed of constable = 8 km/h = $8\times{\frac{5}{18}}$ = $\frac{20}{9}$ m/s
Relative speed of constable = $(8−6)\times{\frac{5}{18}}$ = $\frac{5}{9}$ m/s

Question : If $\cos\theta = \frac{x^2\:-\:y^2}{x^2\:+\:y^2}$, then the value of $\cot\theta$ is equal to:

Option 1: $\frac{2xy}{x^{2}\:-\:y^{2}}$

Option 2:

$\frac{2xy}{x^2\:+\:y^2}$

Option 3:

$\frac{x^{2}\:+\:y^{2}}{2xy}$

Option 4:

$\frac{x^{2}\:-\:y^{2}}{2xy}$

Team Careers360 20th Jan, 2024

Correct Answer:

$\frac{x^{2}\:-\:y^{2}}{2xy}$


Solution :
Let right angle triangle at B and $\angle C = \theta$.
$\cos \theta = \frac{\text{Base}}{\text{Hypotenuse}} = \frac{CB}{AC} = \frac{x^{2}\:-\:y^{2}}{x^{2}\:+\:y^{2}}$
Applying Pythagoras' theorem, $(x^{2}+y^{2})^{2} =(x^{2}-y^{2})^{2}+(\text{Height})^{2}$
$⇒x^{4}+y^{4}+2x^{2}y^{2} =x^{2}+y^{2}-2x^{2}y^{2} +(\text{Height})^{2}$
$⇒4x^{2}y^{2} = (\text{Height})^{2}$
$⇒\sqrt{4x^{2}y^{2}} = \text{Height}$
$⇒2xy = \text{Height}$
So, $\cot\theta = \frac{\text{Base}}{\text{Height}} = \frac{x^{2}\:-\:y^{2}}{2xy}$
Hence, the correct
