Answer:
12.5 feet
Step-by-step explanation:
how to:
lets find the angle that corresponds with the 10 foot side.
to do that we add 50 degrees plus 90 degrees (right angle) to get 140 degrees.
as we know, a triangles angles will total 180 degrees, so 180 - 140 = 40 degrees for the angle corresponding to the 10 foot side.
put these into ratios:
<u>Angle A </u> = <u>Angle B</u>
side a side b
now plug in our numbers:
<u>50 degrees</u> = <u>40 degrees</u>
X 10 feet
Cross multiply:
50 (10 feet) = 40 (x)
solve for x:
500 = 40 (x)
500/40 = x
12.5 = x

Answer:
Option C: 6x is the correct answer.
Step-by-step explanation:
Given that:
Number of books checked each week = x
Number of weeks = 6 weeks
To find the number of books checked in 6 weeks, we will multiply the number of weeks with number of books checked per week
Total books = 6x
Hence,
Option C: 6x is the correct answer.
