I believe x is 30 degrees.
The equilateral triangle has each angle equal to 60 degrees. So the small arc near x is also 60. The angle x is half the arc so would be 30.
This also makes sense because the triangle it forms with angle x and the center has center angle of 60 and angle formed by tangent and radius of 90. So it is a 30-60-90 triangle, making angle x 30.
Do the diameter of the rectangle the divid that by 2 and them multiply that time three
So if you take 42/100 you get .42
Then you take .42 and multiply it by 28
Giving you the answer of 11.76
