Answer:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:
The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the sun
Starting point: (0, 2) and can go to (1, 6).
This shows the slope and y-intercept. Hope this helps.

Step-by-step explanation:
Letter c
For S if the ratio is 2:7 and you use 20 drops of red paint you multiply 2 by 10 which is 20 so you also multiply 7 by ten to get 70 (So the answer for S is 70 drops) and for L you multiply 2 by 20 to get 40 so you multiply 7 by 20 and you get 140 (The answer for L is 140 drops) For T you multiply 2 by 1.5 to get 3 so you multiply 7 by 1.5 which is 10.5 ( so the answer for T is 10.5 drops)
We know that the triangle is made up of 180°
To find "x" we need to know the two angles of the triangle.
We also know that the supplementary angles are made of 180°
In this case the supplementary angle would the angle were 100° and the missing value is.
Since supplementary angles are made of 180°
180°-100° = 80°
Now we know the two angles of the triangle.
Since the triangle is made up of 180°
180° = x + 70° + 80°
x + 150° = 180°
x = 180° - 150°
x = 30°
