Riley is playing a game that requires rolling a number cube numbered 1-6 and spinning a spinner with 3 consonants and 1 vowel. The sections of the spinner are all the same size.
What is the probability that Riley rolls a number less than 3 and lands on a consonant?

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
