Me figure this problem out! i believe it’s not hard for some people who have learned it.

Given: △abc, ab=15, bd=9 ad ⊥ bc , m∠c=30°. find: the perimeter of the triangle.

At dinner, 2/5 of the people had fish and 1/3 had chicken. if everyone else had lamb, what fraction of the people had lamb? and if 40 people had lamb , calculate the total number of people at the dinner.

Solve - pv + 40 < 65 for v solve 7w - 3r = 15 for r
