Given sin θ = 3/5 what is sec θ?
PIT_PIT [208]

Answer:

5/4

Step-by-step explanation:

To do this you must know that by definition secant is:


sec(\theta)=\frac{1}{cos(\theta)}


Furthermore:

sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}


Based on this information we know that 3 = opposite and 5 = hypotenuse.  Assuming this is a right triangle we can determine the adjacent side by Pythagorean Theorem.

c^2=a^2+b^2

Where c is the hypotenuse, a is adjacent and b is opposite.  Therefore,

c^2=a^2+b^2\\\\a=\sqrt{c^2-b^2} \\\\a=\sqrt{5^2-3^2} \\\\a=4


And so the adjacent side of this triangle is 4.  Going back to the definition of secant we can now know that:

sec(\theta)=\frac{1}{cos(\theta)}=\frac{1}{\frac{4}{5}}=\frac{5}{4}
