Jewel

Rhombus-shaped jewel has an area of 23 mm2, and the edge is long 5.9 mm. Calculate the size of the acute rhombus angle.

Final Answer:

α =  41.4 °

Step-by-step explanation:

S=23 mm2 a=5.9 mm   S = a2 sin α  A=arcsin(a2S)=arcsin(5.9223)0.7218 rad  α=A  °=A π180   °=0.7218 π180   °=41.4  °=41.4=41°2120"
