Question

in each of the following figures , O is the centre of the circle . find the value of x and y.​

Answer 1

Answer:

उस गुलाब को क्या गुलाब दूँ

जो खुद ही एक गुलाब है

Answer 2

Answer:

x= 30cm

y=24cm

Step-by-step explanation:

we know that the tangents drawn from the centre are equal.

therefore y=24cm

name the meeting point of tangents as P

so from ∆OCP (right angled triangle)

(OP)²=(OC)²+(CP)²

OP²= (24)²+(18)²

OP²=576+324

OP²=900

OP=√900

OP=30

since OP is x so x=30cm
