Question : If $\sin A=\frac{2}{3}$, then find the value of (7 – tan A)(3 + cos A).

Option 1: $\frac{61}{3}+\frac{17}{3 \sqrt{5}}$

Option 2: $\frac{61}{3 \sqrt{5}}+\frac{17}{3}$

Option 3: $\frac{61}{3}+\frac{17}{\sqrt{5}}$

Option 4: $\frac{61}{3}-\frac{17}{3 \sqrt{5}}$

Team Careers360 25th Jan, 2024

Correct Answer: $\frac{61}{3}+\frac{17}{3 \sqrt{5}}$


Solution : Given: $\sin A =\frac{2}{3}$
We know that $\sin A=\frac{\text{Perpendicular}}{\text{Hypotenuse}}=\frac{2}{3}$
We know, Hypotenuse2 = Base2 + Perpendicular2
⇒ Base = $\sqrt{3^2-2^2}=\sqrt5$
We know, $\cos A =\frac{\text{Base}}{\text{Hypotenuse}}=\frac{\sqrt{5}}{3}$
And,
⇒ $\tan A=\frac{\sin A}{\cos A}=\ \frac{2}{\sqrt{5}}$
Now,
$\left ( 7-\tan A \right )\left ( 3+\cos

Question : AB is a chord in a circle of radius 13 cm. From centre O, a perpendicular is drawn through AB intersecting AB at point C. The length of OC is 5 cm. What is the length of AB?

Option 1: 24 cm

Option 2: 12 cm

Option 3: 20 cm

Option 4: 15 cm

Team Careers360 24th Jan, 2024

Correct Answer: 24 cm


Solution :
As shown in the given figure,
Perpendicular drawn from the centre of a circle to the chord bisects the chord.
Therefore, AC = BC and $\angle$OCB = 90°
Thus, $\triangle$OCB is a right-angled triangle.
By Pythagoras Theorem,
$OB^2 = OC^2 + CB^2$
$⇒CB^2 =
