Question

Check all that apply. If sec=13/12, then:

Answer 1

Answer
1) TanФ = 5/12
2) CosФ = 12/13


Explanation
SecФ = 1/CosФ

Cos = adjacent/hypotenuse
SecФ= 13/12
cosФ = 12/13

This means that the adjacent is 12 and hypotenuse is 13. 
Opposite = √(13²-12²)
                = √25
                = 5

Tangent = opposite/adjacent
TanФ = 5/12

Sine = opposite/hypotenuse 
SinФ = 5/13

Answer 2

Answer:

1) TanФ = 5/12

2) CosФ = 12/13
