Answer:
42.64°
Step-by-step explanation:
Note: A rhombus has all its sides equal, its opposite angle are equal, its has bigger and smaller diagonal, diagonal bisect the angles and diagonal bisect each other.
From the diagram attached,
sinθ = opposite/adjacent
sinθ = 4/11
θ = sin⁻¹(4/11)
θ = 21.32
Therefore, from the diagram,
The smaller angle of the rhombus = 2θ
The smaller angle of the rhombus = (2×21.32)
The smaller angle of the rhombus = 42.64°
Using the Pythagorean Theorem,
(See attachment)
Let us substitute the values and solve for b in terms of .
Grouping the terms on one side gives,
We now apply difference of two squares to obtain,
,
Testing for some few values greater than 1, we can generate the Pythagorean triples as follows;
