Which of these numbers is prime explane how/why those are prime? 30 31 32 33

30 is divisible by 2 so it is composite

32 is divisible by 2 so it is composite

33 is divisible by 3 so it is composite

31 is prime because it can only be divided by itself and 1

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

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
