We are given with the expression arctan(-sqrt(3)) and asked to evaluate it. In this case, we can use a calculator or the rule of common triangles to answer this question. the value of <span>arctan(-sqrt(3)) is -60. Since negative tan is found in 2nd and 4th quadrant, the angles are 180-60 or 120 degrees and 360-60 or 300 degrees.</span>
A)
A polygon is a closed shape so there must be at least three sides. Therefore, the least value that n can be would be three.

Answer: a=3, b=1
A parallelogram have its opposite sides equal and parallel.
Step-by-step explanation:
SO, the quadrilateral WXYZ have its opposite sides equal as its a parallelogram.
From the given figure the side XY= WZ and XW= YZ, which gives two equations i.e
Equation 1 is 3a-4=a+2 and Equation 2 is b+1=2b
Solving Equation 1 Solving equation 2
3a-a = 2+4 2b-b = 1
2a = 6 b=1
a = 3
So, by solving the two equations a=3 and b=1.
I searched it up, and this is what it showed, hope it helps
