Question

to a circle of radius 4 centimetre draw two tangents which are inclined to each other at an acute angle of 60 degree​

Answer 1

Answer:

2 Rt.angled triangle of which

the angles are 30, 60,90

are formed

See that the angles are in the ratio

1:2:3

then simply we can say that the

sides opposit to them will be

1: v3:2

the side against the ratio given

in the data is 4 cm

Hence, 1:v3:2 becomes 4:4v3:8

ThesidesSides of Rt.angled triangle

are 4,4v3 and 8 cm

we can say that the distance from

centre of the circle that external

point is 8cm, length of tangentis

4 v3cm and radius 4cm
