Question

to construct a pair of tangents of a circle at an angle of 45° to each other ,what angle is needed to be drawn between radii of circle. ​

Answer 1

Answer:

Hope this helps..!!!!!

Answer 2

Answer:

the angle at centre of the circle is 145°

Step-by-step explanation:

a tangent to a circle is perpendicular to the corresponding line joining it and passing through the centre.

we know that the sum of angles in a quadrilateral is 360.

in the given question the angle the pair of tangents make is 45° and the angle at the tangency is 90°

let the angle at the centre be x

then x+90+90+45=360

x=145°
