Find the measure of the exterior angle.
Illusion [34]

Answer:

<em> 108 degrees</em>

Step-by-step explanation:

From the diagram we are given

Interior angles are 2x + 1 and 63 degrees

Exterior angle = 5x -2

The sum of interior angles is equal to the exterior angle

2x + 1 + 63 = 5x - 2

2x + 64 = 5x - 2

2x - 5x = -2-64

-3x = -66

x = -66/-3

x = 22

Get the exterior angle:

Exterior angle = 5x-2

Exterior angle = 5(22) - 2

Exterior angle = 110-2

Exterior angle  = 108 degrees

<em>Hence the measure of the exterior angle is 108 degrees</em>

Which function transforms the graph of y= x^2 so that it is first shifted down 4 units and its then reflected across the y- axis
GaryK [48]

Answer:

Option C. y= ( -x)^2 -4

Step-by-step explanation:

If we have a function f(x) = ax ^ 2 and we want to transform it into a function g(x) that is equal to f(x) displaced c units down on the y-axis, then we must do:

g(x) = f(x) -c

In this case we want to move the function 4 units down, then:

g(x) = f(x) -4\\\\g(x) = x ^ 2 -4

Finally, to reflect the function on the y-axis. must do y = g(-x)

Then we have the following function:

g(-x) = (-x) ^ 2 -4\\\\y = (-x) ^ 2 -4

The answer is option C
