The shadow of a 23-m high building is increasing at the rate of 19 cm/min when the shadow is 15 m long How fast is the distance from the top of the building to the end of the shadow increasing? Let a = the length of the shadow, b = the height of the building, and c = the distance from the top of the building to the end of the shadow. How can the distance between the building and the shadow be found? A. Use the Pythagorean theorem to find c. O B. Add a to b to find c. O C. Multiply a and b to find c. D. Subtract a from b to find c. The distance from the top of the building to the end of the shadow is increasing by 10 cm/min (Type an integer or a decimal. Round to the nearest integer as needed.)
