Which best describes the triangle or the triangles, if any, that can be formed with two sides that measure 5 inches and an angle that measures 60 degrees? two different isosceles triangles no triangle one isosceles triangle one equilateral triangle

Answer with explanation:

Suppose the two sides of triangle are, 5 inches and angle between the two sides is 60 degrees.

We will use cosine formula to find third side.Let side opposite to angle having measure 60 degree, is equal to a inches.

Omitting, a= -5, because side can't be negative.

So, third side = 5 cm.

Means, triangle is equilateral.

If angle between , two sides having measure 5 cm , is not 60 degree, then the triangle will be always Isosceles.

we will sine rule to find remaining measurements.

In this case,also ,triangle is equilateral.

Option D: one equilateral triangle
