This is Geometry: Find the area of a rectangle whose diagonal is 10 feet long and which makes a 55 degree angle with one of the sides.

Question

thewayiam983 · Answer

the rectangle is really two triangles, the diagonal being their hypotenuse
thus, one side of the triangle is sin55=x/10, x =8.19
and the other is cos55=y/10, y=5.7
Thus, the area is xy=(8.19)(5.7)=  46.97
