Question

If the angle between two radii of a circle is 100 degree, the angle between the tangents at the ends of those radii is

Answer 1

The angle between two radii is 100 degree
the angel at the tangent =180-100=80 degree
the angel between tangents at end of radii is 90 degree

Answer 2

Dear Student,

◆ Answer -

80°

● Explanation -

Here, two radii and corresponding tangents at the ends of those radii form a quadrilateral.

As we know, tangents are at right angle to radius, remaining two angles are complementary.

x + 100 = 180

x = 180 - 100

x = 80°

Hence, angle between the tangents at the ends of those radii is 80°.

Thanks dear. Hope this helps you...
