All sides of a rhombus are equal. So the perimeter of the rhombus is P = 4a. a - one side of the rhombus.
40 = 4a
a = 10
Rhombus area formula S = a 2 sin
a - one side of the rhombus
& - angle of the rhombus
sin 30 = 0.5

Is there a formula for the solid angle at each vertex of tetrahedron?
A tetrahedron has four vertices as much as a triangle has three vertices. A tetrahedron therefore can have four solid angles as much as a triangle can have three angles.
Is there a general formula for the solid angle at each vertex of tetrahedron, if the length of each of the six edges are given? As much as one can use the law of cosines to determine the angle at each vertex of a triangle, as long as the lengths of each sides of triangle is given?

Proof of angle Bisector Theorem by Vectors
For Δ A B C, let AD is its internal angle bisector, then we know that A B A C = B D C D and I know that it can be proved by geometry by drawing a line through C parallel to AD and extend AB so that it cuts new line and then use various angles and concept of similar triangle to prove our result. But I was wondering if we can prove it with the help of vectors as well?
If we take position vectors of A,B and C as 0 , b and c respectively , then A D can be taken as λ ( b ^ + c ^ ). Could someone help me to proceed after that or provide some alternate approach through vectors?
