Which relationship in the triangle must be true? triangle a b c is shown. angle a c b is a right angle. the length of side c b is a, the length of side a c is b, and the length of side a b is c. sin(b) = sin(a) sin(b) = cos(90 – b) cos(b) = sin(180 – b) cos(b) = cos(a)

Click an item in the list or group of pictures at the bottom of the problem and, holding the button down, drag it into the correct position in the answer box. release your mouse button when the item is place. if you change your mind, drag the item to the trashcan. click the trashcan to clear all your answers. using the technique in the model above, find the missing segments in this 30°-60°-90° right triangle. ab = 8 bc = 4 cd =
