Answer:
a = 41
b = 90
c = 18
Explanation:
A rhombus is a quadrilateral whose side lengths are equal. An example of a rhombus is a square. Moreover, lines are drawn between the vertices of a rhombus always intersect at 90 degrees and bisect the vertices angles.
With this information, we already know that c = 18, c = 41, anf b = 90.
