(a) 60

(b) 90

(c) 135

(d) 120

8) In ΔPQR, S and T are the mid points of sides PQ and PR respectively. If ∠QPR = 45° and ∠PRQ = 55°, then what is the value (in degrees) of ∠QST?

(a) 80

(b) 85

(c) 90

(d) 100

9) AB is a tangent to a circle with centre Oand point B lying on the circle. If the radius of the circle is 7 cm and the length of AB is 24 cm, then what is the length (in cm) of OA?

(a) 25

(b) 26

(c) 28

(d) 31

10) In the given figure, what is the value of
1 +∠2 + ∠3 + ∠4 + ∠5 + ∠6 + ∠7 + ∠8 + ∠9 + ∠10? (a) 600

(b) 720

(c) 900

(d) 1080  a = 1

hence a = b = c = 1

= 1² + 1² + 1²

= 3    ∠PRQ & ∠QXY are supplementary angle

∵ QXYR is a cyclic quadrilateral.

∠PRQ + ∠QXY = 180° ∠C = 180° – 120° = 60°

∠AOB = 60 × 2 = 120° From mid-point theorem,

ST ∥ QR

∠SQR = 80°

Hence ∠QST = 100°  = 25 cm

For Points with angle 2, 5 &9it can be assumed that they are making a triangle hence, sum of its angles=  ∠2 + ∠5 + ∠9 = 180°

For Points with angle 6, 10, 4 and 7 it can be assumed that they are making a quadrilateral hence, sum of its angles=   ∠6 + ∠10 + ∠4 + ∠7 = 360°

For Points with angle 1, 3, 8 it can be assumed that they are making another triangle hence, sum of its angles=  ∠1+ ∠3 + ∠8 = 180°

Total angle ∠1 + ∠2 + ∠3 + ∠4 + ∠5 + ∠6 + ∠7 + ∠8 + ∠9 + ∠10 = 720
