Answer:

The angle of elevation is 32 degrees.

Step-by-step explanation:

To solve this problem, we first must recognize that the angle of elevation is the angle from the horizontal up to the plane; in other words, from Point C to Point A (where the ? symbol is located). Using this knowledge, we see that there are two other angles inside the same triangle, one measuring 90 degrees (represented by the square) and one measuring 58 degrees.

We must remember that in a triangle, the interior angles must add up to 180 degrees, so we can construct the following equation.

90+58+x = 180, where x is the unknown value

If we simplify the left side, we get

148 + x = 180

Next, we should subtract 148 from both sides to isolate the variable x.

x = 32

Therefore, the angle of elevation is 32 degrees.

Hope this helps!

here is your answer mate.

in triangle ABC

angle ABC + angleBAC + angleACB = 180 Degrees. (angle sum property of triangle)

90 + 58 + angle ACB = 180 degree.

148 + angle ACB = 180 degree.

angle ACB = 180 - 148

angle ACB = 32 degree

the angle of elevation is 32 degrees

Answer:

X and Y = 4

Well, it's a right triangle. The red box means 90 degree angle. So I would say that all the sides are equal.

Part A: The average rate of change between the 2nd and 3rd point is Select a Value Part A: The average rate of change between th

Fofino [41]

Answer:

$Rate = 6$

$Rate = 10$

$Rate = 18$

$Rate = 162$

Step-by-step explanation:

Given

See attachment for table

Solving (a): Rate of change between 2nd and 3rd point on A

The rate of change is calculated as:

$Rate = \frac{y_2 - y_1}{x_2 - x_1}$

In table A, the 2nd and 3rd point is:

$(x_1,y_1) =(1,7)$

$(x_2,y_2) =(2,13)$

So, the average rate of change is:

$Rate = \frac{13 - 7}{2 - 1}$

$Rate = \frac{6}{1}$

$Rate = 6$

Solving (b): Rate of change between 3rd and 4th point on A

In table A, the 3rd and 4th point is:

$(x_1,y_1) =(2,13)$

$(x_2,y_2) =(3,23)$

So, the average rate of change is:

$Rate = \frac{23 - 13}{3 - 2}$

$Rate = \frac{10}{1}$

$Rate = 10$

Solving (c): Rate of change between 2nd and 3rd point on B

In table B, the 2nd and 3rd point is:

$(x_1,y_1) =(2,11)$

$(x_2,y_2) =(3,29)$

So, the average rate of change is:

$Rate = \frac{29 - 11}{3 - 2}$

$Rate = \frac{18}{1}$

$Rate = 18$

Solving (d): Rate of change between 4th and 5th point on B

In table B, the 4th and 5th point is:

$(x_1,y_1) =(4,83)$

$(x_2,y_2) =(5,245)$

So, the average rate of change is:

$Rate = \frac{245 - 83}{5 - 4}$

$Rate = \frac{162}{1}$

$Rate = 162$
