Answer:
sin^-1 (√111)/2√37) = 60°
Option A:
Midpoint of LN = (2, 3)
Solution:
In the given graph we can find the coordinates of L and N.
Coordinates of L = (–2, 3)
Coordinates of N = (6, 3)
Here, 
Let us find the midpoint of the segment LN.
<u>Midpoint formula:</u>


Midpoint of LN = (2, 3)
Option A is the correct answer.
Hence the coordinates of the midpoint of the line segment LN is (2, 3).
Angelica needs to sell 20 TVs.
Steps:
Step 1: You divide 5,000 and 250.
5,000/250 = 20
Check: You multiply 250 and 20.
250 x 20 = 5,000
The building is 76 feet tall. Notice that there's a pair of similar triangles in this diagram: The top of the building, root of the building, and the stake form triangle 1. The top of the tree, root of the tree, and the stake form triangle 2. Since the root of the tree is half way between stake and building, the proportionality between the triangles is 2. Therefore, the building is twice as tall as the tree. 38*2=76.
