1. Use Euclid’s division algorithm to find the HCF of 4052 and 12576.

2. In OPQ right angled at P, OP=7 cm and OQ – PQ = 1 cm,

Determine the value of Sin Q, Tan O.

3. Prove that ü5 is irrational number.

Section-B 3 x 3 = 9

integer is of the form 9m, 9m+1 or 9m+8

5. Prove that Sec⁴ A – Sec²A= Tan⁴ A + Tan² A

6. A straight highway leads to the foot of a tower. A man standing at

the top of the tower observes a car at an angle of depression of

30⁰, which is approaching the foot of the tower with a uniform

speed. Six second later, the angle of depression of the car is found

to be 60⁰. Find the time taken by the car to reach the foot of the

tower from this point.
