- cosine = adjacent/hypotenuse
- tangent = opposite/adjacent
The inverse of those help us find the angle. Notation like arcsine is the same as inverse sine denoted as on many calculators.
The decimal results are approximate.
To find r, first write out the equation:
Next, multiply both sides by 2:
Now, subtract both sides by 4:
Divide both sides by 3:
The answer to this problem is r = 2. Hope this helps and have a phenomenal day!
