Step-by-step explanation:

x^2 + y^2 = r^2 --> r = $\sqrt{(-4)^2 + 5^2}$ = $\sqrt{41}$

cos = x /r = -4 / $\sqrt{41}$

sin = y /r = 5/ $\sqrt{41}$

tan = sin /cos = -5 /4

Why is 12 inches 1 foot a conversion factor ?

Alinara [238K]

I have no better answer than simply, because there are 12 inches in a foot.

By definition a conversion factor is one unit being used to express a group or multiple of another unit. Just like how there are 12 of anything in one dozen. 100 years in one century. 365 days in one year. 100 centimeters in a meter. 4 quarts in one gallon. 10 dimes in one dollar. They are equal to each other and, thus, can be used as conversion factors.
