Question

to draw a pair of tangent to a circle which are inclined to each other at an angle of 75°. it is required to draw a tangent at the end points of those two radii of a circle the angle between them should be.

Answer 1

we know ,
tangent perpendicular upon radius .
form quadiratral by radii and tangents in which two angle is 90 degree .
but sum of all angle in quadratral is 360 degree .

now,
angle between radii + 90 + 90 +75 = 360 angle between radii = 360 -(180+75)
= 105 degree
