Answer 1

the answer is c . sorry if its not right

Answer 2

cos(θ) = ³/₅
cos⁻¹[cos(θ)] = cos⁻¹(³/₅)
θ ≈ 53.13

sin(θ) > 0
sin(53.13) > 0
0.8 > 0

1. tan(θ)
tan(53.13)
1¹/₃
The answer is A.

2. sec(θ)
sec(53.13)
1²/₃
The answer is A.

3. cot(θ)
cot(53.13)
³/₄
The answer is B.

4. csc(θ)
csc(53.13)
1¹/₄
The answer is C.
