Answer:
31.243 units
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. Using the attached figure, it is convenient to find the length of BE as an intermediate step in the solution.
Sin = Opposite/Hypotenuse
sin(30°) = BE/100
BE = 100·sin(30°)
Then ...
Tan = Opposite/Adjacent
tan(58°) = BE/x
x = BE/tan(58°) = 100·sin(30°)/tan(58°)
x ≈ 31.243 . . . . units

<em>Comment on the figure</em>
The intermediate problem in creating the figure was to locate point D. That was accomplished by locating point C on a line at an angle of 58° CCW from the horizontal, using point B as a center. Then D is the intersection of BC with the x-axis. BE is drawn perpendicular to the x-axis.
Use hypotenuse leg theorem.
Answer: the first one is 80 and the second one is 7
Step-by-step explanation:
Solution:
we are given that
Cassie is writing a book. she has to write 336 pages. she wants to finish in 8days.
we have been asked to find how much will she need to write each day?
Since she wants to finish in 8days 336 pages.
It mean she eeds to write daily
It mean she eeds to write daily 42 pages.
