Question

PQ and PR are two tangents to a circle with centre O. If angle QOR = (3x - 8) and angleQPR = (4x - 1), find x.
​

Answer 1

Step 1: Draw a circle with O as center and radius 3.5 cm. Step 2: Mark a point P outside the circle such that OP = 6.2cm. ... Step 4: Draw a circle with Q as center and radius PQ (or 0Q), to intersect the given circle at the points T and T'. Step 5: Join PT and PT'.

Here, PT and PT' are the required tangents.
