Diagonals

Rhombus has two diagonals e=14 dm and f=11 dm.

Calculate the side angle and height of the rhombus.

Correct result:

a =  8.9 dm
α =  76.31 °
h =  8.65 dm

Solution:

a2=(e2)2+(f2)2 a=(14/2)2+(11/2)2=8.9 dm
tanα2=fe α=2arctanfe=2arctan1114=76.31=761852"
sinα=ha h=asinα=8.65 dm



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
