A rhombus has sides of length 10cm, and the angle between two adjacent sides is 76°. Find the length of the longer diagonal of the rhombus |
|
Answer» Answer: LET the LENGTH of ONE of the diagonals be 2x and the other be 2Y, then cos (76/2) = x/10 x = 10 cos 38 = 7.88 CM sin (76/2) = y/10 y = 10 sin 38 = 6.16 cm |
