36,6,-24,-54 arithmetic sequences
astra-53 [7]
Since the values are lowering each time and it is an arithmetic sequence, we can assume that each number is being subtracted by the same number. We can figure this out by setting up an equation taking two values from the sequence.
Let's use 36 and 6
36 - x = 6 which gives us 30. We can check our work by subtracting each value by 30 starting from 36.

A man, 1.5m tall, is on top of a building. He observes a car on the road at an angle of 75°. If the building is 30m, how far is
kolbaska11 [484]

Answer:

The answer to this question is 8.44 m.

Step-by-step explanation:

This problem is best illustrated in the photo below.

First, we must know that the angle stated in the problem is the angle of depression. Angle of depression is the angle between the horizontal and the line of sight of the observer. On the other hand, if the observer is looking upward, then the angle between the horizontal and his line of sight is called the angle of elevation.

Since we have the given angle of depression, we must use its complementary angle to solve for the distance of the car from the building.

Let x = complementary angle of 75°

y = distance of the car from the building

To solve for x,

To solve for y, we need to use a trigonometric function that will relate the adjacent of 15° and the opposite of 15°. Let us look at the mnemonics

SOH: Sine =  

CAH: Cosine =  

TOA: Tangent =  

Therefore we must use the tangent function to solve for y.
