Answer: x=50

Explanation:-

Exterior angles of all polygons add up to 360 degrees.
So, x+20+x+40+2x+2x=360
x+x+2x+2x+20+40=360
6x+60=360
6x=360-60
.:6x=300
x=300/6
x=50

Answer:

The required function is y=18-4x and the graph of the function is shown below.

Step-by-step explanation:

It is given that A vat contains 18 gallons of liquid when a drain pipe opens and the liquid begins to leave the vat at a rate of 4 gallons per hour.

It means the initial liquid in tank is 17 gallons and rate of change is 4 gallons per hour.

y-intercept is (0,18).

Slope is -4.

The liquid in tank is defined by the function

y=18-4x              [\because y=mx+b]

At y=0 the tank will empty.

0=18-4x

x=4.5

The x-intercept is (4.5,0).

Therefore the required function is y=18-4x and the graph of the function is shown below.
