The angles in an actual triangle shaped traffic sign all have measures of 60°. explain how you can use this information to decide whether three given angle measures can be used to form a unique triangle or more than one triangle. plz

If all angles in the triangle are 60 degrees, that means there is but one possible triangle that comes from it: an equilateral, where all side lengths and angle measurements are equal. Since a triangle has three angles, all totaling 180 degrees, the only triangle that can be made is an equilateral

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
