Angle F has what measurement according to the protractor?
2 answers:
Answer: The correction option is B, i.e., .
Explanation:
To find the angle F using protector first we have to study about the protractor.
In a protractor the angles are written in two scales. The angles of outer scale is increased in clockwise direction and the the angles of inner scale are increasing in anticlockwise direction.
The reason behind it is the property of supplementary angles. The sum of angles lie on straight line is always 180 degree.
When we have to find the angle we see the inner angles or inner semi circle or the angle in anticlockwise direction.
From the given figure it is noticed that the angles F lies on and
.
The angle in anticlockwise direction is , therefore, the correct option is B.

Use a graphing tool and you'll see a circle form. This circle has a center of (0,0) and radius of 4. Side note: this equation is equivalent to x^2+y^2 = 16 after you divide everything by 4
Looking at the graph, the smallest x can be is -4. The largest x can be is 4. So the domain in interval notation is![[-4,4]](https://tex.z-dn.net/?f=%5B-4%2C4%5D)
Similarly the range in interval notation is also <span> because the lowest you can go is y = -4. The highest you can go is y = 4</span>
