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

Alycia Zemlak · Accepted Answer

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

Alycia Zemlak · Answer

mâ DEF is 90Â°Step-by-step explanation:It is given that Â D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. Thus, using the distance formula, we haveââand ââAlso, Â ââNow, ââThus, Pythagoras theorem holds.Hence, mâ DEF is 90Â°âÎDEF is right angled triangle which is right angled at E.

the actual answer is 90 Step-by-step explanation:

Alycia Zemlak · Answer

The answer 90 degrees.Step-by-step explanation:DE^2 = 1 + 16 = 17. Â EF^2 = 16 + 1 = 17. Â DF^2 = 9 + 25 = 34. Â Since (DE)^2 + (EF)^2 = (DF)^2, Â  angle E is 90 degrees.

The answer is C

Alycia Zemlak · Answer

DE^2 = 1 + 16 = 17.Â EF^2 = 16 + 1 = 17.Â DF^2 = 9 + 25 = 34.Â Since (DE)^2 + (EF)^2 = (DF)^2,Â Â angle E is 90 degrees.Â DF must be the hypotenuseÂ see attachment below
