Question

in figure 9.38 equal to M equal to angle qps equal to 50 degree and Angle pqr equal to 60 degree find the measure of angle pqr ​

Answer 1

Step-by-step explanation:

angle nrq = 180-50 (linear pair)

nrq =130°

and lpq=180-40

lpq=140°

so,

pqm =180-140

=40°

and

rqn= 180-130

=50°

so angle pqr = 50+40

=90°
