The picture shows a barn door:
what is the length of the support ab?
a. 9 divided by tan 60 degrees
b. 9 sin 60°
c. 9 cos 60°
d. 9 divided by sin 60 degrees

d. AB =  9 divided by sin 60 degrees.

Step-by-step explanation:

Given : picture shown a barn door.

To find  : What is the length of the support AB.

Solution : We have given that CB = 9 feet .

angle = 60°,

We need to find AB ?( hypotenuses)

By the trigonometric ratio = sin( theta) = .

Sin (60) =

Plugging the values of CB = 9

Sin (60 ) = .

On multiplying by AB both sides

AB sin(60) = 9

On dividing by sin(60)

AB = .

Therefore, d. AB =  9 divided by sin 60 degrees.

7

step-by-step explanation:

the answer would be 7

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
