Question

(3)
MRPN is cyclic, R=(5x – 13)° and ZN=(4x + 4)º then,
(i) What is R+ZN? State reason.
(ii) Find the value of x.​

Answer 1

Step-by-step explanation:

R+N= 180°

because opposite angels of cyclic quadrilateral are supplementary .

R+N=180°

5x-13+4x+4=180

9x-9=180

9x-=180+9

9×=181

x=181/9

x=21unit
