Question

If tanθ = 1/3 , then secθ = ?

Answer 1

\[\sin^2x +\cos^2x=1.\]

Answer 2

Tangent = Opposite / Adjacent

(So the missing side is the Hypotenuse, opposite=1, adjacent=3)

You know that:
(Opposite Side)\(\large\color{black}{ ^2 }\)+(Adjacent Side)\(\large\color{black}{ ^2 }\)=(Hypotenuse)\(\large\color{black}{ ^2 }\)

Now, plug in your values
\(\large\color{black}{ 1^2+3^2=x^2 }\)

(Labeling the hypotenuse with 'x' since it is the unknown)

Answer 3

Can you find the hypotenuse for me please?

Answer 4

would it be 100?

Answer 5

I don't know how you get 100 for the hypotenuse.
