Textbook Question
Chapter 10.4, Problem 18P
Given a right triangle that has angles a, b, and 90°, draw a tine segment from the comer where the right ang|e is to the hypotenuse so that this line segment is perpendicular to the hypotenuse, as shown in Flgure 10.92 . The line segment divides the original right triangle into two smaller right triangles. Without measuring, determine the angles in these smaller right triangles. How are these angles related to the angles in the original large triangle? Give a general answer, one that does not depend on the specific values of a and b. Explain your reasoning.

- A ladder 27 feet long leans against a wall and the foot of the ladder is sliding away at a constant rate of 3 feet/sec. Meanwhile, a firefighter is climbing up the ladder at a rate of 2 feet/sec. When the firefighter has climbed up 6 feet of the ladder, the ladder makes an angle of л/3 with the ground. Answer the two related rates questions below. (Hint: Use two carefully labeled similar right triangles.) (a) If h is the height of the firefighter above the ground, at the instant the angle of the ladder with the ground is л/3, find dh/dt= feet/sec. (b) If w is the horizontal distance from the firefighter to the wall, at the instant the angle of the ladder with the ground is л/3, find dw/dt= feet/sec.arrow_forwardTwo cars start moving from the same point.
