Question

in the adjoining figure O is centre of the circle. From the point R seg RMand seg RN are tangent segment touching the circle at Mand N. if(OR)=10cm and radius of the circle=5cm then.
1)what is the length of each tangent segment?


2) what is the measureof∆MRO?


3) what is the measure of ∆MRN?​

Answer 1

Answer:

It is given that seg RM and seg RN are tangent segments touching the circle at M and N, respectively. Tangent segments drawn from an external point to a circle are congruent. Thus, the measure of ∠MRO is 30º. Thus, the measure of ∠MRN is 60º.
