Simple...

you have: The angles are supplementary..what is the measure of angle x?

Remember, supplementary means 180°

4x+20+40=180

4x+60=180

4x+60=180
-60 -60

4x=120

x=30

Thus, your answer.

Answer:

Distance between mall and library is 6.32 miles.

Step-by-step explanation:

Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).

Since, distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

By this formula,

Distance between (2, 4) and (8, 4) will be,

Distance = $\sqrt{(8-2)^2+(2-4)^2}$

= $\sqrt{36+4}$

= $\sqrt{40}$

= 6.32 miles
