Question

in the following figure point A is the center of the circle line MN is tangent at point M. if AN=10cm and MN=5cm determine radius of the circle ​

Answer 1

Step-by-step explanation:

by phythagorus theorem we get the answer

AN^2=(AM)^2+(MN)^2

Answer 2

Answer:

5√3cm

Step-by-step explanation:

In circle centred at A , AM is radius MN is tangent

AN=10cm

MN=5cm

AM=?

In AMN,. Mis right angle

According to Pythagoras theorem

AN^2=AM^2+MN^2

10^2=AM^2+5^2

100=AM^2+25

AM^2=100-25

AM^2=75

AM=√75

AM=5√3

Radius is 5√3cm
