Answer:
24°
Step-by-step explanation:
The angle between the vertical line AB and the horizontal dashed line at A is 90°. That is, ...
66° + ? = 90°
? = 90° -66° = 24°
The angle of depression is 24°.

<em>Additional comment</em>
The sum of angles in the triangle is 180°, so the angle at C (the angle of elevation) is the same as the angle we just figured:
∠C + 90° +66° = 180°
∠C +66° = 90° . . . . . . . subtracting 90°; shows C is complementary to 66°
∠C = 90° -66° = 24°
As a rule, the angle of elevation and the angle of depression are the same.
Hi!
Subtracting a negative number is the same as adding a positive.
So instead of
5 - (-1)
We could write
5 + 1
5 + 1 = 6
The answer is 6.
Hope this helps! :)
Since there is no options, i will list several reasons that help bloggers decide how to present information :
- Audience expectation
- Blogger's point of view and personal principle
- The actual fact that blogger has
Yes. In fact, that is basically the definition of a derivative. It is the instantaneous rate of change of a function.
For example, picture the graph of the following function:
The slope is constantly changing at every x-value, so to find the slope at x=a, we find the derivative of the function.
Once we have the derivative, simply plug in a for x to find the slope of the line tangent to f(x) at x=a.
For example, at x=5:
The slope of f(x) at x=5 is 10.
Answer:
0.68
Step-by-step explanation:
10^-2 is 0.1 10 and go to the left 2
0.1 * 6.8 = 0.68
