the sides of a parallelogram are 4.0cm and 6.0cm. One angle is 58 degrees while another is 122 degrees. Find the lengths of the diagonals of the parallelogram.

I got one diagonal as 5.2 and the other as 8.8

answer should be 7.211...did you figure out it was a right triangle?

i just did the formula u gave me for the other problem with the two angles to find the lengths of the diagonals

but did you realize that the we are using in this case is in which case the formula I gave you reverts back to the pythagorean theorem since the elminating the last term
