Answer:
Step-by-step explanation:
From the previous answers you know the angles and side lengths of the triangle:
α = 60°
Ф = 30°
and the side lengths:
1,2 and √3.
Remember:
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
Now you can read off from the triangle:
sin 30° = 1/2
cos 60° = 1/2
sin 60° = √3/2
cos 30° = √3/2
tan 30° = 1/√3
tan 60° = √3
8000 + 300 + 70 + 4 + 0.2 + 0.01
Point slope form
y - -6 = (-1/2)(x - -4)
y + 6 = (-1/2)x - 2
y = (-1/2)x - 8
Answer: y = (-1/2)x - 8
Check. Clearly slope is -1/2, good. (-1/2)(-4)-8=2-8=-6 good
