To solve this problem, we must consider all the trigonometric equations:
⇒ (see image below)
Let's examine the diagram:
- the side adjacent to ∠A ⇒ AC ⇒ 35 meters
- hypotenuse ⇒ 53 meters
Thus we can use:
[tex]cos(A)=\frac{35}{53} \\A= cos^{-1}(\frac{35}{53})\\ A = 48.67[/tex]
Answer: 49 degrees (as rounded)
Hope that helps!
