Question

In the given figure, if PQ || RS, then find the measure
of m​

Answer 1

Answer:

PQ||RS

hence,angle QPS=angle PSR=43°

Now by angle sum property of triangle ram

angle m=180°-70°=110°

Answer 2

angle S =43 degree(alternate interior angles)

angle m lies within the triangle mRS

so angle m +angleR+angle S=180degree(sum of all angles of a triangle is 180 degree

27+43+m=180

70+m=180

m=180-70

m=110 degree
