A store charges $68.95 for a pair of cowboy boots. The store can calculate total cowboy boot sales by using the equation t=68.95

IgorLugansk [536]

Well to find the total sales you must substitute for the variable in the equation;

t = 68.95b

t = 68.95(31)

t = 2,137.45

So the total of the store's boot sales is;

$2,137.45

Find the cosine of angle p

zlopas [31]

Answer: last option

Step-by-step explanation:

You need to remember the identity:

$cos\alpha=\frac{adjacent}{hypotenuse}$

You need to find the cosine of angle P, then, you can identify in the figure that:

$adjacent=PR=21\\hypotenuse=PQ=29\\\alpha=P$

Therefore, the next step is substitute these values into $cos\alpha=\frac{adjacent}{hypotenuse}$ , then you get:

$cos(P)=\frac{21}{29}$

You can observe that this matches with the last option.
