should be A. because 36 plus 144 is 180, and that is the degree of the straight line that both the degrees are on. Hope this helps, whymenotsmart^m^.

The top angle in he triangle is 180o - 121o  =  59o.

The angle in the right corner of the triangle is 180o - 144o  =  36o.

This means that the angle in the left corner of the triangle is 180o - (59o + 36o)  =  85o                 

To find the value of no:  no  =  180o - 85o  =  95o.

All exterior angles add up to 360 degrees so we have 360-121-144=95 so our final answer is 95o
