Diagonals 5113

In the diamond KLMN, the lengths of the diagonals are 10 cm and 6 cm. Determine the angle size that the longer diagonal makes with the side of the diamond.

Correct answer:

X =  30.9638 °

Step-by-step explanation:

u1=10 cm u2=6 cm a=u1/2=10/2=5 cm b=u2/2=6/2=3 cm x=arctan(b/a)=arctan(3/5)0.5404 X=x  °=x π180   °=0.5404 π180   °=30.964  °=30.9638=30°5750"
