I don't see any other relation to use.
By triangle exterior angle theorem, we have the three angles of a certain triangle are such that the first angle is 20 % less than the second angle, and the third is 20% more than the second angle.
The three examples below show how angle relationships and the properties of triangles can be used to find unknown angles. If we know the measures of two angles in a triangle, we can use the triangle sum theorem to find the measure of the third angle. The law of sines states that sina (angle a) / a (side a) = sinb/b=sinc/c. Learn how to find the missing sides or angles of a right triangle when one length and one angle is provided.
