When working out an equation, if the result comes out like : x = 2, or y = 4.....a variable equal to a number, then there is 1 solution
if the result comes out like : 0 = 4, or 2 = 6...no variable and an incorrect result, then the equation has no solutions because ur lines are parallel.
if the result comes out like : 2 = 2 or 5 = 5...no variable and a true statement, then there will be infinite solutions because ur lines are coincident...they are the same line
The area would be 62 you would add if those together to get 62 mm (sorry if it’s wrong)
Answer: A
Step-by-step explanation:
This is the concept of trigonometry, the sine, cosine and tangent of 11/6 pi radians will be as follows;
11/6pi=11/6*180=330
thus;
tan 330=-0.5774
sin 330=-0.5
cos 330=-0.8660
