Question

In the triangle below, calculate the sec J.

Answer 1

secant is the opposite of cos

cos=adj/hyp

sec=hyp/adj

Answer 2

so from angle J, identify your adj side and hypotenuse

Answer 3

I think that the adjacent side is g and the hypotenuse is h.

Answer 4

correct

Answer 5

hmmm that triangle has missing units there

but as dtan5457 said, use SOH CAH TOA \(\bf sin(\theta)=\cfrac{1}{csc(\theta)}
\qquad

% cosine
cos(\theta)=\cfrac{1}{sec(\theta)}
\qquad

% tangent
tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}
\)

Answer 6

hmmm actually, I meant to post \(\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}
\qquad

% tangent
tan(\theta)=\cfrac{opposite}{adjacent}\) anyhow

Answer 7

Thank you, both of you! (^_^) I think that I understand it now.
