Question

If BC = 6.5, CD = 7.8, and AD = 12.2, find AB to the nearest tenth.

Answer 1

Not enough information is given. Is ABCD is a quadrilateral with two internal angles = 90°, then it would be possible to calculate AB.
However, Angle C could be 88° and Angle C could be 92° which would give the length of AB another value.

Answer 3

So, re-draw that here and label all of your given

Answer 4

U use pythagorean theorem to find the length of AC and when u find it u use what u got and use pythagorean theorem again to find the lenght of AB

Answer 5

^ not given that it is right so you cannot use pythag without proving right ∆ first

Answer 6

i got confused ????

Answer 7

please: re-draw that here and label all of your given so we can do the problem

Answer 8

@FibonacciChick666 there
