The angle of depression calculator. How to find the angle of depression?

Since we now know what the angle of depression is, let's learn how to find it! We can determine the angle of depression using surveying equipment like an engineer's transit or a clinometer. These devices are optical instruments that have angle-measurement features and can instantly give us the angle that we need. However, we can also use mathematics to find the angle of depression. But first, we need to know two distances: the horizontal distance between the viewer and the object, and their vertical distance, as shown in the illustration below:

Answer:

83.15

Step-by-step explanation:

Joey's current grade can be determined by weighting his scores with the weights given and adding the results

Tests = 0.6 x 82 = 49.2

Quizzes = 0.25 x 77 = 19.25

homework = 0.15 x 98 = 14.7

49.2 + 19.25 + 14.7 = 83.15

Answer:

3a² + 13ab - 10b²

Step-by-step explanation:

(3a - 2b)(a + 5b)

Each term in each bracket multiplies each term in the other bracket.

3a(a + 5b) -2b(a + 5b)

3a² + 15ab - 2ab - 10b²

3a² + 13ab - 10b²

Okay so first you want to simplify the given equation  (7x+3y)(7x-3y)

in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2

Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2

Its as easy as pie!

Answer:

60

Step-by-step explanation:

A Batman scored the following runs

58, 73, 21, 77, 99, 32

The mean can be calculated as follows

= 58+73+21+77+99+32/6

= 360/6

= 60

Hence the mean is 60

Multiply: 6 (children) • 2.15 (cost per ticket) = 12.90

Add: 12.90 + 4.90 = £17.80

Answer:

the answer is B or q^2t^5/p^3

Answer:

Step-by-step explanation:

Let the starting point be B and the stopping be C as shown in the diagram below.

therefore, the angle at A will be (197-90)degree = 107degree

the angle at B is 45degree, since it is directly south west of C.

therefore the angle at C will be A+B+C=180 degree(sum angle of a triangle)

107+45+C=180

therefore, C=180-107-45=28degree

therefore, using sine rule gives;

sinA/a =sinC/c

sin107/a=sin28/4

0.9563/a=0.4695/4

0.9563/a=0.11736

therefore, a =0.9563/0.11736=8.148=8.1km(approx.)

The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6 thus options (A) and (B) are correct.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

As per the given equation,

3x² - 3x + 1

To find the roots of the above quadratic equation,

3x² - 3x + 1 = 0

x = [-(-3) ± √((-3)² - 4×3×1)]/(2×3)

x = [3 ± √(-3)]/6

x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6

Hence "The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6".

The required equation of green and blue line is y = 3x- 4 and y = x+1

The standard equation of a line is expressed as y = mx + b

where;

m is the slope

b is the y-intercept

Note that the y-intercept is the point where the line cuts the y-axis

From the graph, the y-intercept of the green line is 3 while that of the blue is 1. This shows that the required equation of green and blue line is y = 3x- 4 and y = x+1

Answer:

side length of 2

side length of 6

side length of 7

Step-by-step explanation:

So remember the two shorter lengths added together have to be greater than the longest side length

For the first answer choice we add 7 and 8

7+8=15

The two shorter sides added are not greater then the longest side so that is not the answer

For the second answer choice we add

8 and 5

8+5=13

13 is not greater than 14 so this is not the answer choice either

For the third one we add 6 and 3

6+3=9 which is not greater than 10 so this is not the answer

For the last one we add 2 and 6

2+6=8 which is greater than 7 so this one is the answer

Answer:

D.

Step-by-step explanation:

The area of a shape is the amount of space on the shape.

The area of the shaded region is 819 inches square

Start by calculating the area of the sector using:

[tex]A = \frac{\theta}{360}*\pi r^2[/tex]

So, we have:

[tex]A = \frac{150}{360}*\frac{22}{7} * 27.8^2[/tex]

[tex]A = 1012.05[/tex]

Next, calculate the area of the isosceles triangle using:

[tex]A = \frac 12 r^2\sin(\theta)[/tex]

So, we have:

[tex]A = \frac 12 * 27.8^2 * \sin(150)[/tex]

[tex]A = 193.21[/tex]

The shaded area is the difference between the areas of the sector and the triangle.

So, we have:

[tex]A = 1012.05 - 193.21[/tex]

Calculate the difference

[tex]A = 818.84[/tex]

Approximate

[tex]A = 819[/tex]

Hence, the area of the shaded region is 819 inches square
