Answer 1

this is ur answer

hope it's help you

Answer 2

Answer:

sec θ  = $\frac{5}{4}$ ; cos θ = $\frac{4}{5}$

Step-by-step explanation:

tan θ = $\frac{3}{4}$

sec θ = √1 + tan²θ

         = $=\sqrt{1+(\frac{3}{4})^2} \\\\= \sqrt{1+\frac{9}{16} } \\\\=\sqrt{\frac{16+9}{16} } \\\\=\sqrt{ \frac{25}{16}} \\\\=\frac{5}{4}$

cos θ = $\frac{1}{Sec }$θ

         $=\frac{1}{\frac{5}{4} } \\\\=\frac{4}{5}$
