Answer:
- 1) 19.07 m, 2) 80.10 ft, 3) 56.79 m
Step-by-step explanation:
Use <u>trigonometry</u> to solve for unknowns.
<h3>1) Use sine</h3>
- <em>sine = opposite leg / hypotenuse</em>
- sin 27° = x/42
- x = 42 sin 27°
- x = 19.07 m (rounded)
<h3>2) Use tangent</h3>
- <em>tangent = opposite leg / adjacent leg</em>
- tan 23° = 34/x
- x = 34 / tan 23°
- x = 80.10 ft
<h3>3) Use cosine</h3>
- <em>cosine = adjacent leg / hypotenuse</em>
- cos 48° = 38/x
- x = 38 / cos 48°
- x = 56.79 m (rounded)
