using the law of sines, the approximate length of the tree is calculated as: C. 45 ft.
<h3>What is the Law of Sines?</h3>
The law of sines is given as: sin A/a = sin B/b = sin C/c, which is used to solve a triangle.
Given the following:
- H = the length of the tree = ? (b)
- Let sin A = 30°
- a = 25
- Sin B = 65°
Apply the law of sines
sin 30/25 = sin 65/H
H = (sin 65 × 25)/sin 30
H ≈ 45 ft.

Answer:
x = 13
Step-by-step explanation:
3x + 4x-1 +90 = 180
7x = 91
x = 13

2/5x=3/4-1/3
2/5x=9-4/12
2/5x=5/12
x=25/24
Answer:
1. The top choice.
2. The third choice.
3. The third choice.
Step-by-step explanation:
Number one is a line, so it should have two arrows.
Number 2 is a segment, so it should have no arrows.
Number 3 is a ray, so it should have one arrow. (The letters need to be in the same direction as the ray, hence why it is BC and not CB)
