Answer:
<h2>15°</h2>
Step-by-step explanation:
We know that the central angle of a circle is 360°.
In this case, we have the circle divided into 12 equal parts, so each angle would be also the 12th part of 360°.
Each circular sector has an angle of 30°, and each arc is equal to 30°.
Now, notice that tha angle formed by the two blue cables is an external angle formed by two secants, that means we can use the following relation
Where 
is the angle formed by the two blue cables.
Therefore, the angle measures 15°.
The average change per hour is B 40.7
Answer:
It is a linear function.
Step-by-step explanation:
The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.
To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).
This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.
Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2). Slope intercept is y=mx+b.
The line of the equation would then be y = -2/3x -2
Answer:
45°
Step-by-step explanation:
- For this question, I'll name the "?" angle as x to avoid confusion.
- x and 45 are EQUAL to each other because they are corresponding angles
x = 45
To find the area, first, find the length and width. Given, length = 15 units and width = 4 units. The formula to find the area of a rectangle is A = l × w.
