So the problem is to find the two diagonals of the rhombus. First your givens are the parallel sides are 30 cm each and the angle are 60 degrees each. First you want to find out what equation can you use from the givens. To proceed this step you will need the function of Tan(degree)=Sinx/Cosx. You know that the degree is 60 degree and that the sin(x) will be x and that the cos will be 30 cm. (It would help if you drew the Rhombus), therefore, you would get Tan(60)=x/30. Now find x, multiply 30 to Tan(60). so Tan(60)*30=x. Therefore, the x will be 51.96cm or approximately 52 cm.
