The size of a cell is typically found by capturing an image under a microscope then using software to measure its diameter. Two cells are measured using this method:Cell B: 9.71\times 10^{-2}9.71×10−2centimetersCell C: 6.72\times 10^{-3}6.72×10−3centimetersWhat's the difference between the diameters of the two cells? Express your answer using either standard notation or scientific notation.

c is the correct answer

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
