Answer:
y=1-7x
Step-by-step explanation:
7x+y=1
The first thing to do is get the y by its self. So u cancel the 7x out by-7x and bring it to the other side.
7x-7x = 0
Now all we have left is: y=1-7x
Hope it helps and is right.
Answer:
120°, 150°
Step-by-step explanation:
the first polygon has 6 sides, and has an interior angle sum of 720°. you then divide that by 6 to get a single angle. The second polygon has 12 sides and a total of 1800°, which is then divided by 12 to get the single angle.
None of these. All of these functions are defined as ratio of trigonometric functions.
Trigonometric functions have infinite zeroes, so when you put them in the denominator, they lead to infinitely many points of ill-definition.
Specifically, we have:

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
