Step-by-step explanation:
I got this. Bottom of the triangle. that flat line is 180 degrees. you have an angle of 120, leaving an angle of 60. if you look at the top, that angle matches the other. so you have 65 degrees on one side, and 60 on the other. so 180-65-60=55. so X=55

is the equation used for determining area from radius. We're given diameter, so to get the radius simply divide by 2. 19/2 = 9.5.

, when solved, equals

. After rounding to the nearest tenth, we get
