Solve BCD Round the answer to the nearest hundredth

Mathematics
1 answer:
lesya [120]3 years ago
7 0

Answer:

A

Step-by-step explanation:

The measure of angle D can be found using the Interior Angle Sum of a Triangle.

The angles of a triangle add to 180. This means:

90 + 21 + x = 180.

111 + x = 180

x = 69

The solution is A.

Angle B is smaller than Angle D which means CD will be smaller than BC.

The smallest region that can be photographed is
5*7 = 35 square km
so we want to know how long it takes to zoom out to an area of
35 * 5 = 175 square km.

Notice that the length and width increase at the same rate, 2 km/sec, and they start out with a difference of two, so when the width has increased from 5 to x, the length will have increased from 7 to x+2. At the desired coverage area, then,
x(x+2) = 175
x^2 + 2x = 175
x^2 + 2x + 1 = 176 [completing the square]
(x+1)^2 = 176
x+1 = ±4√11
x = -1 ±4√11

Since a negative value for x is meaningless here, x must be
-1 + 4√11 = about 12.27 km
and the time it took to increast to that value was
(12.27 - 5) km / (2 km/sec) = about 3.63 seconds
