Question

In a circle of radius 4cm if the angle between the tangents to the circle is 900 then the length of the tangent is A) 2cm B) 8cm C) 6cm D) 4cm​

Answer 1

Answer:

a) 2 is the answer for above question

Answer 2

Answer: Length of tangent is 4 cm.

Step-by-step explanation:

Tangent is a line which intersects the curve at exactly one point.

From every point outside a circle, two tangents can be drawn on the circle.

Both tangents have the same length.

Both the tangents equal angles from the center.

In the given question,

Length of tangent = r cot(45°) = 4  cot(45°)  = 4 cm
