XYZ RST Triangle is similar to triangle such that X, Y, and Z correspond to R, S, and T, respectively. ∠Z 20° 2XY = The measure of is and RS. What is ∠T the measure of? 2°
Correct answer: C (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice C is correct. It’s given that triangle XYZ is similar to triangle RST, such that X, Y, and Z correspond to R, S, and T, respectively. Since corresponding + angles of similar triangles are congruent, it follows that the measure of Z is + + 20° congruent to the measure of T. It’s given that the measure of Z is . + 20° Therefore, the measure of T is . 44 SAT PRACTICE TEST #9 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n MATH: MODULE 2 Choice A is incorrect and may result from a conceptual error. Choice B is + incorrect. This is half the measure of Z. Choice D is incorrect. This is twice the + measure of Z.
