A line is a collection of points.
Here is the graph i’ve created to answer your question!
What are numbers used though? I can’t answer if you don’t say the full problem because there aren’t any units or numbers.
Answer:
4.2 ft
Step-by-step explanation:
Reference angle = 77°
Opposite side = DE = x
Hypotenuse = CD = 4.3 ft
Apply the trigonometric function of sine. Thus:
Sin 77 = opp/hyp
Sin 77 = x/4.3
Multiply both sides by 4.3
4.3 × sin 77 = x
x = 4.2 ft (nearest tenth)
