What is the value of sec A (include steps)

17/15

Step-by-step explanation:

Sec A = 1/ Cos A

Cos A = Adjacent / Hypotenuse

1/Cos A = Hypotenuse / Adjacent

So, Sec A = Hypotenuse/Adjacent

= AB/AC

= 17/15

17/15

Step-by-step explanation:

Secant is the inverse of cosine.

Cosine is the adjacent side divided by the hypotenuse.

cos A = 15/17

sec A = 17/15

-0.3n + 0.6

Step-by-step explanation:

if we write out the entire expression we have:

0.5n - 0.3 - 0.8n + 0.9 (two negative signs create a positive sign)

then we add and subtract

and receive

-0.3n + 0.6
