Q
4. If PQ and PR are the two tangents to a circle
with centre 'o' so that LRPQ =70°
then LROQ=_
b) 100° C)70° d) 90°
a) 110°
​

Answer 1

Answer:

a)110°

Step-by-step explanation:

the sum of opposite sides of a quadrilateral formed by tangents = 180°

so,

angle RPQ + angle ROQ = 180°

70° + ROQ = 180°

ROQ = 180° - 70°

ROQ = 110°
