A zip line was installed at an outside playground. It is 15.5 m long and attached to two posts 15 m apart on a flat ground. Given that at the arrival post, the zip line must be 1.5 metres above the ground, at what height should it be attached to the other post? Give your answer correct to one decimal place.
Yara is a set designer. She wants to use two wooden pieces, a square and a right triangle , which are attached together along by hinges. She wants to place them on the floor, as shown in the figure, and make sure that the two pieces form a right angle. If this is the case, then any line in the triangle is perpendicular to , and any line in the square is perpendicular to . She has no tool with her except a measuring tape.
She measured the length of and found it to be 42 cm. Is the angle between the square and the triangle a right angle?
