Question
The angle between two radii of a circle is 95°,then find the angle between the tangents at the end of the radii?
Open in App
Solution
The tangents and radii will form a quadrilateral...
sum of all angle of quadrilateral =360 deg
Two angles of quadrilateral become 90 deg ( since the angle made by tangents to radii =90,tangents are perpendicular to radii)
third angle is given as 95 degree
so fourth angle = >
Fourth angle+ 90+90+95=360
Fourth angle = 360-90-90-95
=85 degree
sum of all angle of quadrilateral =360 deg
Two angles of quadrilateral become 90 deg ( since the angle made by tangents to radii =90,tangents are perpendicular to radii)
third angle is given as 95 degree
