Step-by-step explanation:
'sin' is the ratio of the opposite side to the hypotenuse of the given angle in a right angled triangle
Sample Response: If the data is collected in a biased manner, the graph could be skewed. Also, if the number of observations is too small, the graph can be skewed. To ensure the data is not skewed, collect a large representative unbiased sample
Use the quadratic formula to solve it:

a= -6
b= 100
c= -180
x = [-b +- sq root(b^2 - 4ac)] / 2a
