In order to use the Law of Sines, EF has to be the included side. Therefore, we need to calculate angle F which is 72 degrees.
side f / sine (F) = side d / sine (D)
side f / sine (72) = side 24 / sine (45)
side f = sine (72) * 24 / sine (45)
side f = 0.95106 * 24 / .70711
side f (DE) =

answer is C
Hey there!
The x-intercept would be positive 3 because it is the opposite of -3 in the equation.
And the y-intercept would be -4.
I hope this helps you :)

Well this type of problems isn't exactly my strong suit, but I tried to come up with a solution, so my reasoning is as follows: we know that 1km is 0.621 miles, and the problem incites us to find how much time 1 mile takes, so we need to find how many kms are in a mile:
1km ---> 0.621 miles
<=> 1/0.621=1.610 km ---> 0.621/0.621 = 1 mile
so 1 mile = 1.610 km
Next we need to know how much time 1.610 km takes to run across
We know that:
10 km take 55 mins
and 1.610 = 10/6.211
so we need to divide 55 by the same value
55/6.211 = 8.855 mins
So 10 km ---> 55 mins
1.610 = 10/6.211 km ---> 55/6.211 = 8.855 mins
I hope I didn't mess up.
Hope I helped ^^
