Question

Geometry. (ss below)

Answer 1

SOH CAH TOA

we will be using CAH, since we are given the adjacent(the top side) and the hypotenuse.

\[ \cos \theta =\frac{17.8}{37.4} \]
\[ \theta = \cos (\frac{17.8}{37.4}) \]
\[ \theta= \cos 0.47 \]
\[ \theta = 61.579 \Rightarrow \theta \approx 61.6^\circ \]

which option is that?

Answer 2

I honestly don't know. You've confused me even more.

Answer 3

Okay. Thanks, i guess.

Answer 4

oh i just noticed -- i mean:

\[ \theta= \arccos 0.4759358 ~~~~~~(\text{reverse of cos)} \]
\[ \theta = 61.579 \Rightarrow \theta \approx 61.6^\circ \]
