Check all that apply, if csc theta=13/5, then: a. sec theta= 5/13 b. tan theta= 5/12 c. sin theta= 5/13 d. cos theta= 5/13

csc θ = 13/5

When you flip both sides:

sin θ = 5/13

If you know the Pythagorean triples, it will be 5, 12, and 13. Otherwise you could do a² + b² = c²

You can use:

which is

Or you could draw a triangle, either way works.

To find tangent, you know 13 is the hypotenuse because it is the longest side, and 5 is "opposite" so 12 is "adjacent. So:

tan theta = 5/12

And cosine is adjacent/ hypotenuse, so it is:

cos theta = 12/13

sec theta is the opposite of cos theta, so it is:

sec theta = 13/12

B and C are correct

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

it's d
