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

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

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
