Your answer is incorrect. On a survey, 6 students reported how many minutes it takes them to travel to school. Here are their responses.
10, 14, 10, 13, 14, 13
Find the mean travel time for these students.
If necessary, round your answer to the nearest tenth

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
