The isosceles triangle has 2 equal sides of 4 inches and a vertex angle measure of 70 degrees, and it is a unique triangle
How to determine if the triangle is unique?
The given parameters are:
Triangle type = Isosceles triangle
Side length = 4 inches
Angle measure = 70 degrees
Since the triangle is an isosceles triangle, then the equal angles would be:
Ф = 180 - 2 * 70
Ф = 40
The length (L) of the third side is:
L/2 = 7 * cos(40)
Multiply both sides by 2
L = 14 * cos(40)
L = 10.7
So, the angles in the triangle are 70 and 40 degrees; while the side lengths are 4 and 10.7 inches
