Answer:
Step-by-step explanation:
using sin formula
![\frac{sin~E}{15} =\frac{sin ~90}{39} \\sin ~E=15 \times ~\frac{1}{39} =\frac{5}{13}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin~E%7D%7B15%7D%20%3D%5Cfrac%7Bsin%20~90%7D%7B39%7D%20%5C%5Csin%20~E%3D15%20%5Ctimes%20%20~%5Cfrac%7B1%7D%7B39%7D%20%3D%5Cfrac%7B5%7D%7B13%7D)
The answer is 2700 cubic feet. Hope this helps!
Answer:
250 questions
Step-by-step explanation:
65 is equal to 26% of the total number of questions so:
65 / total number of questions (x) is equivalent to 26 / 100
(65 and 26 are a fraction of the whole thing. it doesn't matter whether they go on the numerator or denominator, as long as they are either both on one or the other)
65/x = 26/100
you can simplify this into
26x = 6500
/26 /26
then you divide by 26 on both sides to isolate the variable
x = 250
