Question

Construct two tangents to a circle of 3cm radius with 50 °

Answer 1

Step-by-step explanation:

1. Draw a circle of radius 3 cm. OA = 3 (Fig. 1)
2. Draw ∠AOB and ∠AOC of 65° each. [65 = (180 - 50) / 2] (Fig. 2)
3. Draw perpendicular lines to OB and OC. Let the point at where these perpendicular lines meet be D. ∴ ∠BDC = 50° (Fig. 3)

Hope this may be helpful.

Thank you. Have a nice day.
