A spinner has equal regions numbered 1 through 21. What is the probability that the spinner will stop on an
even number or a multiple of 3?

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Write the expression as a constant , a single trigonometric function, or a power of a trigonometric function. sin x cos x/ tan x
