First off, rewrite all of the fractions so that they have a common denominator. That's 2/12, 2/12, and 4/12. Adding these together, we get 8/12. That's the probability of getting an A, B, or C — but not a D. The chance of getting a D is represented by the remaining 4/12 — or 1/3.

TIn short, the chance of rolling D is exactly 1/3.

A man on a 135-ft vertical cliff looks down at an angle of 16°13' and sees his friend.

A) Use the trigonometric function and ratio cos(x) = A/H. (Adjacent/Hypotenuse)
1. cos(x) = 135/H
2. H*cos(16°) = 135
3. H = 135/cos(16°)
***Make sure calculator is in degree mode***
4. H = 140.44 ft (rounded to two decimal places)
________

b) Use the function and ratio tan(x) = O/A (Opposite/Adjacent)
1. tan(x) = O/A
2. tan(16°) = O/135
3. 135*tan(16°) = O
4. O = 38.71 ft (two decimal places)

Good luck!

We can observe that the function describing the graph is linear and so the equation is of linear nature:

$y=mx+n$
