Answer:
Diagonals of the rhombus = 10 cm and 8 cm,
Area of the rhombus = 10*8/2 = 40 sq cm.
Side of the rhombus = [5^2+4^2]^0.5 = 6.403124237 cm.
Perimeter of the rhombus = 4*6.403124237 = 25.61249695 cm.
Distance between opposite sides = 40/6.403124237 = 6.246950476 cm.
Acute angle of the rhombus = 2*arc tan (4/5) = 77.31961651 deg.
Obtuse angle of the rhombus = 2*arc tan (5/4) = 102.6803835 deg.
Inradius = 6.246950476/2 = 3.123475238 cm.
