(a) 20
(b) 20√3
(c) 40
(d) 60
Answers :
1) Answer: A
As base are same
∴ 5a – 3 = -17 + 3a
2a = – 14
a = – 7
2) Answer: A
Put x = 0
⇒ 1
3) Answer: C
4) Answer: D
5) Answer: B
6) Answer: D
As P is circumcenter
∴ ∠BAC = ½ × ∠BPC
=15°
7) Answer: A
∴ Radius of the circum – circle = 13/2=6.5
8) Answer: A
QO = OR
∴ ∠ORQ = ∠OQR = 45°
And ∠PQR = 30° + 45° = 75°
∴ ∠POR = 2 × ∠PQR
= 2 × 75
= 150°
9) Answer: C
10) Answer: B
