If you don't know, don't answer

the area of a rectangle is 7.7682 x 104 cm2 and the width is 2.42 x 102 cm. what is the length?

To find the length, divide the area by the width:

7.7682 x 10^4 / 2.42 x 10^2

Hen dividing scientific numbers, divide the real numbers and then subtract the exponents:

7.7682 / 2.42 = 3.21  ( since there is only 1 number to the left of the decimal point, we don't need to worry about converting it to scientific order).

4-2 = 2

The answer becomes 3.21 x 10^2 cm

the correct answer is the second option

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
