Question

If a pair of tangents to a circle of 5cm radius is inclined at an angle of 90° find length of tangent

Answer 1

Answer:

Tangents are of 5 cm

Step-by-step explanation:

As given in the figure:

LQRP = 90° (GIVEN)

LOQR &LOPR=90° (the tangent at any point of a circle is perpendicular to the radius through the point of contact)

==> LQOP=90°

HENCE OQRP IS A SQUARE

Since all the sides of a square are equal,

OQ=QR=PR=OP

here OQ and OP are the radii which is equal to 5cm

==>Tangents QR &PR = 5cm

Please pardon me for my flaws
