Question : Two chords AB and CD of a circle with centre O intersect at P. If $\angle$ APC = 40º, then the value of $\angle$AOC + $\angle$BOD is:

Option 1: 50º

Option 2: 60º

Option 3: 80º

Option 4: 120º

Team Careers360 26th Jan, 2024

Correct Answer: 80º


Solution :
The angle subtended by a chord at the centre is twice the angle subtended on the circumference. 
$\angle$BOD = 2$\angle$BCD
⇒ $\angle$AOC = 2$\angle$ABC
⇒ $\angle$AOC + $\angle$BOD = 2($\angle$BCD + $\angle$ABC)
The sum of the interior angle is equal to the exterior angle.
$\angle$BCD

Question : If $x\cos \theta -y\sin \theta =\sqrt{x^{2}+y^{2}}$ and $\frac{\cos ^2{\theta }}{a^{2}}+\frac{\sin ^{2}\theta}{b^{2}}=\frac{1}{x^{2}+y^{2}},$ then the correct relation is:

Option 1: $\frac{x^{2}}{b^{2}}-\frac{y^{2}}{a^{2}}=1$

Option 2: $\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1$

Option 3: $\frac{x^{2}}{b^{2}}+\frac{y^{2}}{a^{2}}=1$

Option 4: $\frac{x^{2}}{a^{2}}-\frac{y^{2}}{b^{2}}=1$

Team Careers360 26th Jan, 2024

Correct Answer: $\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1$


Solution : $x\cos \theta -y\sin \theta =\sqrt{x^{2}+y^{2}}$ ..................................(1)
$\frac{\cos ^2{\theta }}{a^{2}}+\frac{\sin ^{2}\theta }{b^{2}}=\frac{1}{x^{2}+y^{2}}$ .......................................(2)
From equation (1),
$\frac{x\cos \theta}{\sqrt{x^{2}+y^{2}}} -\frac{y\sin \theta}{\sqrt{x^{2}+y^{2}}} =1$
Comparing with $\cos^2 \theta + \sin^2 \theta = 1$, we get,
$\sin \theta = -\frac{y}{\sqrt{x^{2}+y^{2}}}$ and $\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}}$
Putting in (2),
$\frac{x^2}{(x^2 +
