Question 10(multiple choice worth 1 points) (07.01 mc) the picture shows a barn door: a barn door has two parallel bars. a support ab runs across the diagonal between the two parallel bars. the angle made by the diagonal with the parallel bar on top is 60 degrees. the distance between the two parallel bars is 9 feet. what is the length of the support ab? 9 divided by tan 60 degrees 9 sin 60° 9 cos 60° 9 divided by sin 60 degrees

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
