Remember "SOH CAH TOA"
Sine = (Opposite/Hypotenuse)
Cosine = (Adjacent/Hypotenuse)
Tangent = (Opposite/Adjacent)
In this case, we will be using cosine, and our equation will be 
So firstly, cross-multiply. 
Next, divide both sides by cos(28), and your answer will be 
Any
in this set will be real numbers that are both less than
and greater than
. But that's not possible, so this set is empty.
Answer:
The expression means that X+20
Answer:
1 inch = 82 miles
Step-by-step explanation:
You can divide each of the terms of this ratio by 14 to get the ratio for 1 inch:
14 in : 1148 mi
= (14 in)/14 : (1148 mi)/14
= 1 in : 82 mi
The graph that represents the function is graph b. Graph b is the only graph the appropriately represents the y intercept (the value of y when x = 0).
