Solve the given problems.A car passes directly under a police helicopter 450 ft above a straight and level highway. After the car travels another $50.0 \mathrm{ft}$, the angle of depression of the car from the helicopter is decreasing at $0.215 \mathrm{rad} / \mathrm{s}$. What is the speed of the car? See Fig. 27.20 .

Okay, so then there's unable to find X, and so we're gonna because I wanna about trigonometry functions. But for the angle, let's look at the angle. He would have an angle of depression, which is 18 1 day, but we don't want to use that number one to use whatever this angle is because we want the angle inside of the triangle. Now, since this is writer angled a brain and go plus the I think +13 with equal a 90 to have 18.3 was excessive Court 90 Till then exclude equal of 71.7. So this is 71.7 and now we can find X that we have the opposite side of the adjacent. We're gonna be using tangent opposite over 14.3. We multiplied by 14.3 so you would listen or calculator. We get that X would then be 43 want to readers, and that's the answer
