Geometry B Unit Test Reviews Questions and Answers Already Graded A Given right triangle RST, what is the value of sin(S)? 5/13 Given △ABC, sin(A) = cos(c) To support a tree damaged in a storm, a 12-foot wire is secured from the ground to the tree at a point 10 feet off the ground. The tree meets the ground at a right angle. At approximately what angle does the wire meet the ground? 56.4° Given △ABC ~ △XYZ, what is the value of cos(Z)? 12/13 The equation tan(55°) = 15/b can be used to find the length of AC. What is the length of AC? Round to the nearest tenth. 10.5 Given right triangle QRS, what is the value of sin(30°)? 1/2 The equation cos(35°) = a/25 can be used to find the length of BC. What is the length of BC? Round to the nearest tenth. 20.5 The longest side of an isosceles obtuse triangle measures 20 centimeters. The other two side lengths are congruent but unknown. What is the greatest possible whole-number value of the congruent side lengths? 14 cm Kari is flying a kite. She releases 50 feet of string. What is the approximate difference in the height of the kite when the string makes a 25o angle with the ground and when the string makes a 45o angle with the ground? Round to the nearest tenth. 14.2 feet Building A and building B are 500 meters apart. There is no road between them, so to drive from building A to building B, it is necessary to first drive to building C and then to building B. About how much farther is it to drive than to walk directly from building A to building B? Round to the nearest whole number. 183 meters Which equation can be used to find the measure of angle LKJ? sin-1(8.9/10.9) = x Which is the best approximation for the measure of angle ABC? 58.3° A theater production group is making frames to support wall-like props. Three-foot beams form right triangles with 10-foot beams to allow them to stand, as shown in the image. What is x, the angle at which the diagonal beam meets the 10-foot beam at the top of the frame? 16.7° Two sides of an acute triangle measure 5 inches and 8 inches. The longest side is unknown. What
