Hello from MrBillDoesMath!
Answer:
sqrt(15)/4
Discussion:
The attachment shows a right triangle where arcsin(@) = 1/4. (The arcsin means find the angle whose sine is 1/4 as is done in the triangle.) The missing side, sqrt(15), shown in red, was determined by the Pythagorean theorem.
Then cos(@) = cos(arcsin(1/4)) = sqrt(15)/4
Thank you,
MrB
Draw the line somewhere between the -1 and the zero on the horizontal line
The area of a triangle is half times base times height
Which his half times six times eight which is twenty four
The width is 3 feet. If you set up your equation like so...
lwh = A
(4) (2) (w) = 24
Then proceed to divide 24 by 4 and 2.
(4) (2) (w) = 24
/4 /4
2w = 6
/2 /2
w = 3 feet
