Find the value of "X". If a factory produces three products, pen, pencil and eraser in the ratio 2 : X : 7. When this information illustrated on pie chart, the angle of the sector that represents the quantity of eraser produced is 140 degree.

The point (-7, -24) is on the terminal ray of angle 0 which is in standard position. a student found the six trigonometric values for angle e. the student's answers are shown. which value(s) are incorrect? sin(8) cos(8) 24 tan(0) sin(0)=25 cos(0) -- tan(ⓡ) - - 24 csc(o)=2 sec(0) --25 cot(6) - za csc(o) sec(0) cot(0) done
