Expert Answer
In the figure, POQ is a straight line. So, it forms a straight angle or 180o angle
Therefore, we have
angle POR plus angle ROQ equals 180 degree
left parenthesis 3 straight x plus 20 right parenthesis degree plus left parenthesis 4 straight x minus 36 right parenthesis degree equals 180 degree
7 straight x minus 16 equals 180
7 straight x equals 196
straight x equals 28
