Aresearch company surveys 8,000 people. the company expects 6,000 people torespond favorably. if there is a percenterror of 2.5%, what is the range ofpeople who will respond favorably to thesurvey?

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

Hope this ; )
