my attempt...since angle NRP is 138, and arc NMP = 138 x 2 is an intercepted arc.
so then arc NRP is 360 - 276 = 84 degrees.
how come in the book there is an answer that does not have solution ... then the answer is 112 degrees.
Kindly help me on this..
thank you.. there is lacking in the solution that is why i was confused but your solution helped me a lot.
Since arc MN is 136 so the angle NPM is 1/2 ( 136) = 68... the angle NPM and NPQ form linear pair, 180 - 68 = 112 for the measure of the angle NPQ.
Thank you Sir Plato.
