Correct Answer: 27°

Solution : We have to find $\angle AOB$.
In quadrilateral APBO,
$\angle A = \angle B = 90°$
Now, $\angle P + \angle A + \angle B + \angle O = 360°$
⇒ $54° + 90° + 90° + \angle O = 360°$
⇒ $\angle O =

Correct Answer: $\frac{m^2-1}{m^2+1}$

Solution : $1 + \sin\theta = m\cos\theta$
⇒ $m=\frac{1}{\cos\theta}+\frac{\sin\theta}{\cos\theta}$
⇒ $m=\sec\theta+\tan\theta$
Squaring both sides, we get,
⇒ $m^2 = \sec^2\theta + \tan^2\theta + 2\sec\theta\tan\theta$
We know, $\sec^2\theta = 1+\tan^2\theta$
⇒ $m^2 = 1+\tan^2\theta + \tan^2\theta + 2\frac{\sin\theta}{\cos^2\theta}$
⇒ $m^2 = 1+2\frac{\sin^2\theta}{\cos^2\theta} +2\frac{\sin\theta}{\cos^2\theta}$
⇒ $m^2 = \frac{\cos^2\theta +2\sin^2\theta
