The ratio of the width to the length of a flower bed is 10 : 19. how long is the flower bed if its width is 6 feet?

11.4

Step-by-step explanation:

10:19  

6 : X  

Cross multiply, 10X = 114  

Divide both sides by 10 to get X

Make sure to move decimal once and you get 11.4

step-by-step explanation:

the angles look like they are complementary. without more information, you cannot be sure that they are.   so the two angles may or may not add up to 90o. since you can't be sure, don't choose b

the angles certainly are not supplementary. they don't look like they add up to 180 degrees. and they are not marked in a way that would tell you that.

they are not vertically opposite. for one thing they are not equal which vertically opposite angles are.

the only suitable answer is a adjacent angles -- not a really common term, but nothing else works.
