Question

A rhombus has diagonals of lenth 12 cm and 7 cm respectively. Find the larger angle of the rhombus

Answer 1

The diagonals are perpendicular, and they bisect each other. So, you have 4 right triangles with legs 6 and 3.5

The diagonals bisect the vertex angles, so the angle is

2arctan(6/3.5)
