Answer:

Step-by-step explanation:
Since Θ is in fourth quadrant then cosΘ > 0, as is secΘ
Given
sinΘ = -
, then
cosΘ = 
=
=
= 
Hence
secΘ =
= 
The answer is sqrt17 or 4.123
Ok so to solve to first one u do this:
62.4 - 31.53, which gives u 30.87. and then u add 30.87 and 31.33, and u get 62.4
for the second one u do the same thing.
Answer:no
Step-by-step explanation:
Because you have two -2 in the x slots , if you see an number more than once it is no longer a function.
I think 2/4 but I'm not 100% sure sry
