Web30 mrt. 2024 · 37. A straight highway leads to the foot of a tower. A man standing at the top of the tower observes a car at an angle of depression of 3 0 ∘, which is approaching the foot of the tower with a uniform speed.Six seconds later, the angle of depression of the car is found to be 6 0 ∘.Find the time taken by the car to reach the foot of the tower from this point. WebSince it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem. For the same reason, if m∠B < m∠C, then AC < AB. This is a contradiction to what is given. hakho hero fragile
