Question

if two tangents inclined at an angle 60° are drawn to a circle of radius 4 cm then what is the length of each tangent?​

Answer 1

The answer to this question is available in CLASS 10 TEXT BOOK from lesson CONSTRUCTION .

Answer 2

Answer:

centre of the the circle and point of intersection of both the tangents are joined { Construction }

So both angles will 30 degrees

So, Tan 30 degree = radius / length of tangent

1/root 3 = 4 cm / length of tangent

length of each tangent = 4root3 cm
