Step-by-step explanation:
We are given that:
Where <em>A</em> is in QI.
And we want to find sec(A).
Recall that cosecant is the ratio of the hypotenuse to the opposite side. So, find the adjacent side using the Pythagorean Theorem:
So, with respect to <em>A</em>, our adjacent side is 63, our opposite side is 16, and our hypotenuse is 65.
Since <em>A</em> is in QI, all of our trigonometric ratios will be positive.
Secant is the ratio of the hypotenuse to the adjacent. Hence:
Answer: 36 three-point field goals.
Step-by-step explanation:
To solve this problem, set up a system of equations. Let's call the number of one-pointers , the number of two-pointers
, and the number of three-pointers
. We are trying to find
here. We also know that
, because that is the total amount of baskets, and also that
, which is the total amount of points. We know that there were 22 free throws, so that means we can take away 22 baskets from the first equation, and also 22 points from the second equation. Now the equations are
and
. Solving the equations using our knowledge of systems of equations, you get that
. So, 36 is the answer. Let me know if anything was unclear, and I hope this helped.
