B, If you times each number by two, you will get the next number.
Answer:
21.3 feet
Step-by-step explanation:
In the right triangle Δ ABC, the ∠ C = 90° and ∠ A = 25°.
Now, length of BC = 9 inches and length of the hypotenuse i.e. AB is c that we have to calculate.
Now, using trigonometry we can say that
![\sin 25^{\circ} = \frac{BC}{AB} = \frac{9}{c}](https://tex.z-dn.net/?f=%5Csin%2025%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7BBC%7D%7BAB%7D%20%3D%20%5Cfrac%7B9%7D%7Bc%7D)
⇒
feet ≈ 21.3 feet. (Answer)
