Question

In the given figure, RQ is tangent with centre at O. If SQ = 8 cm, QR = 3 cm find OR

Answer 1

Answer:

Step-by-step explanation:

sq=6cm = oq=3cm

qr=4cm , since rq is a tangent to the circle at q

angle rqo=90 {tangent is perpendicular to the radius of a circle

in triangle rqo, {pythagores theorem}

or^2 = qr^2 + oq^2

or^2 = 4^2 + 3^2

or^2 = 25

or = 5cm
