From the top of a 150 m high-rise building, two cars on the same road below the building are seen at an angle of depression of and on each side of the building. Find the distance between the two cars to the nearest meter.

Step-by-step explanation:

The question is incomplete.

Find attached the picture with the complete question including the diagram.

The second figure shows the construction of two right triangles with common height of 150m.

To find the distance between the two cars, you can calculate the horizontal leg of each right triangle.

1. For the triangle on the left side of the picture:

Naming x the horizontal leg:

2. For the triangle on the right side of the picture:

Since it is a 45 - 45 - 90 triangle, the horizontal leg has the same lenght as the other leg, which is the height of the building: 150m

3. Distance between the two cars:

Round to the nearest meter. That is 237m. ← answer

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
