.
26. (A)In 𝛥ABC, D, E and F are midpoints of BC,CA and AB respectively. Prove that △𝐹𝐵𝐷 ∼ △ DEF and △ DEF ∼ △ ABC .
OR
(A) In 𝛥ABC, P and Q are points on AB and AC respectively such that PQ is parallel to BC. Prove that the median AD drawn from A on BC bisects PQ.
.
27. The sum of two numbers is 18 and the sum of their reciprocals is 9/40. Find the numbers.
.
28. If 𝛼 and 𝛽 are zeroes of a polynomial 6𝑥^2 -5x+1 then form a quadratic polynomial whose zeroes are 𝛼^2 and 𝛽^2.
.
29. If cosθ + sinθ = 1 , then prove that cosθ - sinθ = ±1
.
30. (A) The minute hand of a wall clock is 18 cm long. Find the area of the face of the clock described by the minute hand in 35 minutes.
OR
(B) AB is a chord of a circle centred at O such that ∠AOB=60˚. If OA = 14 cm then find the area of the minor segment. (take √3 =1.73)
