Question 23 of 25

Answer 1

Answer:

C

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos37° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{15}$ ( multiply both sides by 15 )

15 × cos37° = x , then

x ≈ 12 ( to the nearest integer )

Answer 2

Answer:

$x$ rounded to the nearest integer would be 12.

Step-by-step explanation:

In order to calculate the length of $x$, you can use the law of sines, a trigonometry rule used to solve the angles and sides of a right triangle. The law of sines states that the sine of an angle in a triangle divided by its opposite side is equivalent to all other angles taken to their sines and divided by their opposite sides. Using this rule, we can now calculate the length of $x$. In this case, $\frac{sin(90^{o})}{15} = \frac{sin(53^{o})}{x}$ ⇒ $\frac{15}{sin(90^{o})} = \frac{x}{sin(53^{o})}$ ⇒ $x=\frac{15*sin(53^{o})}{sin(90^{o})}$ ⇒ $x=15*sin(53^{o} )$ ⇒ $x$ ≈ 12. So side $x$ rounded to the nearest integer would be 12.
