Question

helo please!!

Answer 1

Always remember that for a right triangle:


you use the trigonometric ratios(also known as SOH, CAH TOA):

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

Answer 2

wow i really dont get this one like i cannot even guess the answer

Answer 3

\(\LARGE \theta\) represents any angle (A or C, since B is already the 90°).
you can apply the trig ratios on each choices to find which ratio will satisfy \(\LARGE \frac{a}{c}\).

As you can see, \(\LARGE \frac{a}{c}\) is same as \(\LARGE \frac{opposite}{adjacent}\), so it means that it should be a \(tangent\) ratio. You just have to find out what angle will satisfy \(\LARGE tan\ \theta=\frac{opposite}{adjacent}=\frac{a}{c}\). Look at the diagram, which angle is the opposite of side \(a\)?
