Question:
Solution:
Considering the data in the figure, we can use the following trigonometric identity:
[tex]\tan (49)\text{ = }\frac{opposite\text{ side}}{\text{adjacent side}}=\text{ }\frac{x}{11}[/tex]
that is:
[tex]\tan (49)\text{ = }\frac{x}{11}[/tex]
now, solving for x we get:
[tex]x\text{ = tan(49) x 11 = 12.654}[/tex]
then, we can conclude that the correct answer is:
[tex]x\text{ = 12.654}[/tex]
