Since the legs are the same length, we know that the remaining two angles must be the same.
120+2x=180
2x=60
x=30
Final answer: x=30 degrees

Answer: Option A.
Step-by-step explanation:
You need to use this formula for calculate the surface area of the right cylinder:
Where "r" is the radius and "h" is the height.
You can identify in the figure that:
Knowing this, you can substitute these values into the formula , therefore you get that the surface area of this right cylinder is:
