D(5,7), e(4,3), and f(8,2) form the vertices of a triangle. what is m a-30 b-45 c-60 d-90

Question

Given the points D(5,7), E(4,3), and F(8,2) as the vertices of a triangle, what is the measure of angle A if the possible options for its measure are: a) 30°, b) 45°, c) 60°, d) 90°?

DE^2 = 1 + 16 = 17. EF^2 = 16 + 1 = 17. DF^2 = 9 + 25 = 34. Since (DE)^2 + (EF)^2 = (DF)^2, angle E is 90 degrees. DF must be the hypotenuse Here look at that
