A rhombus has a 60 degree angle and sides 5 cm. long. What is the area? Round your answer to the nearest tenth

Answer 1

5 * 5 * sin(60 degrees) = 25sqrt(3)/2

that rounds to 21.7

Answer 2

the rhombus is particularly 2 issoceles triangles joined at the same time by making use of their shortest edge. so the portion of a the rhombus would be two times the portion of one of those triangles the portion of the triange is got here upon by making use of 0.5 AB sin C, so the portion of the rhombus could be ABsinC that's, 5*5*sin60 this equals 12.5*root 3
