You are packing for a road trip and you buy snack packages (same size, same weight) for the trip. You buy 6 potato chips, 5 doritos, and 3 corn curls. You put them in a bag and mix them up. During the trip, you reach into the bag and pull out two packages at random, one at a time. Draw a tree and calculate the probability of each outcome. Use P for potato chips, D for doritos, and C for corn curls. What is the probability of picking two snacks of the same type?

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
