D 837.5 is the right answer
This one is the Law of Sines again.
The Law of Sines relies on the standard labeling of triangle ABC with vertices A, B, and C and respective opposite sides of a, b and c. Then

Here we have A=150 degrees (opposite side a), b= 10 cm and B = 12 degrees. We seek a.
So we need the first equation of the Law of Sines:



Answer:
Step-by-step explanation:
By the polygon exterior angle sum theorem, all the exterior angles of a polygon add up to equal 360 regardless of the number of sides it has. That means that 82 + 150 + b = 360 so
b + 232 = 360 and
b = 128
Answer:
24
Step-by-step explanation:
Answer:
Step-by-step explanation:
If the price is linear, then the slope between each pair of points must be the same.
m = Δy/Δx
m = (150 - 70) / (5 - 1) = 20
m = (450 - 150) / (20 - 5) = 20
m = (1050 - 450) / (50 - 20) = 20
So the equation is indeed linear. It has a slope of 20 and y-intercept of 50.
p = 20n + 50
