What is a possible value of sin(theta) when cos2(theta)=0.21 a) 0.32 b) 0.37 c) 0.63 d) 0.63

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

faster, im not sure why but i know it is faster
