777dan777 [17]

Answer:

8.95feet

Step-by-step explanation:

The set up is a right angled triangle where;

The camera's horizontal distance from the focus point = 26feet = Adjacent;

The height of the camera above the floor = Opposite = x

Angle of elevation = 19°

According to TOA in trig identity;

Tan theta = opp/adj

Tan 19 = x/26

x = 26tan 19

x = 26(0.3443)

X = 8.95feet

Hence the camera is placed at a height of 8.95feet above the floor

What is 28 tiles in 7 ros. (It has to be a divison equation)
raketka [301]

If 28 tiles is placed in 7 rows then each row has 4 tiles.

<u>Step-by-step explanation:</u>

The total number of tiles given =28.

The number of rows = 7.

The number of tiles in each row is given by diving the total number of tiles given by the number of rows.

No of tiles in each row= \frac{total number of tiles}{number of rows}.

No of tiles in each row = \frac{28}{7}.

No of tiles in each row = 4.

Note: You can replace the values according to the given values.
