IMO, answer is C.

The information given indicates that RST is an equilateral triangle making $$x^{\circ} = 180^{\circ} - {\angle}SRT = 180^{\circ}-60^{\circ} = 120^{\circ}$$

The triangle is equilateral. Hence, all angles are 60 degrees. Since angle x is created by merely extending RT, we can conclude that the measure of x is 180-60 = 120 degrees

given a equilateral triangle .... all sides at 60.
x = 180 - 60 = 120

Equilateral triangle means all angles = 60

so x =180 -60 =120

RS=ST=TR implies the triangle is an equilateral triangle with each angle 60.

we know that x+60 =180 as they are angles on the line. So x=120.

Since we have an equilateral triangle, each interior angle is 60 degrees, and thus x = 180 - 60 = 120.

Answer: C

As RS= ST=TR , it is equilateral triangle with each angle measures 60.

So, x = angle RST + angle STR (An exterior angle of a triangle is equal to the sum of the opposite interior angles)
= 60 +60
= 120
