Sec(theta) = 1 / cos (theta) = hypotenuse / x -coordinate
hypotenuse = 1 (because it is the radius of the unit circle)
sec (theta) = 1 / (-3/5) = - 5/3
cot (theta) = 1 / tan(theta) = x-coordinate / y - coordinate
cot (theta) = -3/5 / y
y^2 + (-3/5)^2 = 1 => y^2 = 1 - 9/25 = 16/25 = y = +/- 4/5
Third quadrant => y = -4/5
=> cot (theta) = (-3/5) / (-4/5) = 3/4
Formula for trapezoid area is A=b1+b2 x heightx 1/2 so your answer would be 161m squared
I think it's 9 but I could be wrong
18.386 rounded to the nearest hundredth would be 18.39
Answer:
4³=4*4*4 is a required expanded form.
