An observer at the top of a tower of height 20m sees a man due to east of him at an angle of depression of 27 degree. he sees another man due to south of him at an angle of depression of 30 degree. find the distance between the men on the ground

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
