Is the sequence 3, 12, 36, a geometric sequence?

No

Step-by-step explanation:

In a geometric sequence there is a common ratio. The common ratio is the number that when multiplied by a number in the sequence gives you the next number. To find the common ratio, you divide any number by the previous number. Every division must give you the same answer, the common ratio.

Now try to find the common ratio of this sequence.

36/12 = 3

12/3 = 4

The ratios between terms are not equal. There is no common ratio.

Therefore, this sequence is not a geometric sequence.

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
