Explanation:
The purpose of trigonometry and the trigonometric ratios sine, cosine, and tangent is to help you <em>calculate</em> angles based on the ratios of side lengths of triangles they are found in.
Answer:
The difference between value of y at x=11 is 385, the correct option is third
Step-by-step explanation:
y = -- X + 4 and you can go from there
Supplementary angles add up to 180 degrees
a + b = 180
a = 4b
4b + b = 180
5b = 180
b = 180/5
b = 36 <=== here is 1 angle
a = 4b
a = 4(36)
a = 144 <== and here is the other one
