Which statement(s) are true based on the Pythagorean identities?

What is sine (theta)

Which identity can you now use to find cos(t)?✔ cos(t) = 1 / sec(t) cot(t) = 1 / tan(t) X tan(t) = sin(t) / cos(t)

What is cos(t)?

-8/17-15/178/17✔ 17/8

-15/8-15/17✔ -8/158/17

Which identity would be best to start with?sin²(t) + cos²(t) = 1✔ tan²(t) + 1 = sec²(t)1 + cot²(t) = csc²(t)
