Q. $\mathrm{ABCD}$ is a trapezium such that $\mathrm{AB}$ and $\mathrm{CD}$ are parallel and $\mathrm{BC} \perp \mathrm{CD} .$ If $\angle \mathrm{ADB}=\theta, \mathrm{BC}=$
$\mathrm{p}$ and $\mathrm{CD}=\mathrm{q},$ then $\mathrm{AB}$ is equal to
(1) $\frac{\left(p^{2}+q^{2}\right) \sin \theta}{p \cos \theta+q \sin \theta}$
(2) $\frac{p^{2}+q^{2} \cos \theta}{p \cos \theta+q \sin \theta}$
(3) $\frac{p^{2}+q^{2}}{p^{2} \cos \theta+q^{2} \sin \theta}$
(4) $\frac{\left(p^{2}+q^{2}\right) \sin \theta}{(p \cos \theta+q \sin \theta)^{2}}$

Q. If the angles of elevation of the top of a tower from three collinear points A, B and C, on a line leading to the foot of the tower, are $30^{\circ}, 45^{\circ}$ and $60^{\circ}$ respectively, then the ratio, AB : BC, is:
(1) $1: \sqrt{3}$
(2) 2 : 3
(3) $\sqrt{3}: 1$
(4) $\sqrt{3}: \sqrt{2}$

(1) 5 (2) 6 (3) 10 (4) 20

**[JEE(Main)-2016]**
Q. Let a vertical tower AB have its end A on the level ground. Let C be the mid-point tanis equal to :-
(1) $\frac{4}{9}$
(2) $\frac{6}{7}$
(3) $\frac{1}{4}$
(4) $\frac{2}{9}$

**[JEE(Main)-2017]**
Q. PQR is a triangular park with $\mathrm{PQ}=200 \mathrm{m}$. A T.V. tower stands at the mid-point of $\mathrm{QR} .$ If the angles of elevation of the top of the tower at $\mathrm{P}, \mathrm{Q}$ and $\mathrm{R}$ are respectively $45^{\circ},$ $\left.30^{\circ} \text { and } 30^{\circ}, \text { then the height of the tower (in } \mathrm{m}\right)$ is-
(1) 50
(2) $100 \sqrt{3}$
(3) $50 \sqrt{2}$
(4) 100

We more questions from previous years papers

Very bad ourstion it is not correct improve this ouestion

Thanks for providing this

superb

sir this esaral is providing a very gud set of questions…

but its need to update a little, we the students are ariving 2020 jee and for that we need latest jee online questions.

these questions are just incomplete
