I'm pretty sure the answer is either A or D
Polar covalent molecules<span> exist whenever there is </span>an<span> asymmetry, or uneven distribution of electrons in a </span>molecule<span>. </span>One<span> or </span>more<span> of these asymmetric atoms pulls electrons </span>more<span> strongly </span>than<span> the </span>other<span>atoms. For example, the </span>polar<span> compound methyl alcohol has a </span>negative<span> pole made of carbon and hydrogen and a positive ...</span>
If an angle of a parallelogram is two-third of its adjacent angle, then the smallest angle of the parallelogram is 72°. Adjacent angles exhibit a common side and a corner point.
Adjacent angles exhibit a common side and a corner point, although they do not overlap.
A parallelogram can be defined as a simple type of quadrilateral having two pairs of parallel sides.
A rectangle can in turn be defined as a parallelogram having four right angles (90°), thereby all rectangles represent quadrilaterals.
The sum of the adjacent angles of a parallelogram is equal to 180°.
In this case, we have that the sum of adjacent angles >> X + 2/3 X = 180° >> X = 108° >> 2/3 X = 72°

Answer:
Answer might be A
Explanation:
I don't know the full passage but from what you wrote about the "Red Grouper, it might be a figurative language.
Cos(2θ) = cos²θ - sin²θ = (1-sin²θ)-sin²θ = 1-2(7/9)^2 = -17/81
