The diagonals of a rhombus separate the rhombus into 4 of the same right triangles. So, we can use trig to find each of those angles. Then, we can find each angle of the rhombus by doubling the angles.
If the diagonals are 7 and 10, then the sides of the triangles are 3.5 and 5. You can use trig various ways to find the angles. I will use the inverse tangent function:
tan(-1) (3.5/5) = 34.99 degrees
tan(-1) (5/3.5) = 55.01 degrees
So, doubling those angles (I will carry all decimal places through, then round to 2 placed):
One angle is 110.02 degrees
The other angles is 69.98 degrees.
