180 degrees is a straight line. It is half of 360 which is a full circle, so if you split the circle in half you'll get a straight line.
There are 4 quadrants and each quadrant is has a measure of 90° angle.
Because the direction is positive, it means that the arm is going from 1st quadrant to 2nd quadrant.
90° + 90° = 180°
Because there is an additional rotation of 25°, the arm is now in the 3rd quadrant.
180° + 25° = 205°
The measure of the angle is 205°
Answer:
87
Step-by-step explanation:
f(x)=19x+11
Let x = 4
f(4) = 19*4 +11
=76 +11
= 87
First find the slope between any two points:

Where

are the two points
So calculating the slope:

So the slope is

And our equation will be in the format of

where

and

So, now we have half of the equation:

Now to calculate b, we can plug in a point

and solve for b.
So

Lets use the point

So:

And then:

So our final equation is
