4 0

Answer:

The choice; B) 5/3

Step-by-step explanation:

{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\  {15}^{2}  +  {20}^{2}  =  {c}^{2}  \\ 225 + 400 =  {c}^{2}  \\  {c}^{2}  = 625 \\ c = 25

\sec(θ)  =  \frac{1}{ \cos(θ) }  \\  \\  \sec(θ)  =  \frac{1}{ \frac{adjacent}{hypotenuse} }  =   \frac{hypotenuse}{adjacent}  \\  \\  \sec(θ)  =  \frac{25}{15}  =  \frac{25 \div 5}{15\div 5}  =  \frac{5}{3}
