Answer:
72°
Step-by-step explanation:
To convert from degrees to radians, multiply the degrees by .
To convert from radians to degrees, multiply the radians by .
Right now you're in radians, so multiply it by .
=
°.
Now we need to find the reference angle for 432°.
If you draw 432° starting from the right and going clockwise (because it is a positive angle, if it was negative you would go counterclockwise), it will make one full rotation, which is 360°, and you will end up in the 1st quadrant, 72° past 360°.
Depending on the quadrant you land in, there might be different operations to perform. Please check the attached image.
In this case, we're in the 1st quadrant so we can leave the angle as is.
The answer is 72°.
Answer:
y = -x + 10
Step-by-step explanation:
To find the equation of a line that passes through the point (8,6) and perpendicular to the equation 2x - y = 4, we will follow the steps below:
first write the equation 2x - y = 4 in a standard form
we will find the slope of our equation using this equation
2x - y = 4
y = 2x -4
comparing the above with
y = mx + c
m = 2
= -1 ( slope of perpendicular equations)
2 = -1
= -1/2
our slope m = -1/2
We can now go ahead and form our equation
=8
=6
y- = m (x-
)
y-6 = -(x-8)
y-6 = -x + 4
y= -x+4+6
y = -x + 10
