Question

In the triangle below, determine the value of a.

Answer 1

Being that this is a right triangle, and since the measurement of angle A is 43 degrees, this means that angle C is 47 degrees. That much I know. Reminder: I'm asking for side a here, not angle A.

Answer 2

right... 47 is correct for C

Answer 3

recall your SOH CAH TOA \(sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

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

so... which one of those fellows have
the angle
the opposite side
and the hypotenuse
only ?
