It's A. Segments that intersect at the right angle
X+y=425. This is as simple it can be, unless theres more information. x is the distance traveled on the first day and y is the distance traveled on the second day.
Answer:
27,720 ways
Step-by-step explanation:
The number of permutations of non-distinct items is determined by the following expression:

If there are five linden trees, four white birch trees, and three bald cypress trees:

The landscaper can plant the trees is 27,720 distinct ways.
Note that the interior angles must add up to 180 degrees: 50+62+m<C = 180.
Then 112 + m<C = 180, so that m<C =68 degrees.
Use the Law of Sines to find the value of a, as follows:
sin 50 deg sin 62 deg
-------------- = ----------------
a 31 cm
31sin 50 31(0.766)
Then 31sin 50 = a*sin 62, and a = --------------- = ---------------- = 26.9 cm
sin 62 0.883
a =
