Answer:
The length of the ramp is at least 17.2 feet
Step-by-step explanation:
See attachment for the appropriate diagram.
The length of the ramp is represented with z
So, we have:


Required
Find z
To find z, we make use of sine formula:

Make z the subject

So:



<em>The length is at least 17.2 feet</em>
4 3/4= 19/4=4.75 its a terminating decimal
\left[x _{4}\right] = \left[ \frac{ - \left( -1\right) ^{\frac{3}{4}}\,\sqrt[4]{\left( 20 - 21\,z^{2}\right) }}{\sqrt[4]{4}}\right][x4]=[4√4−(−1)434√(20−21z2)]

Answer: D
Step-by-step explanation:
(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.
I think C was supposed to be -27/40 so D is the correct answer since it's positive.
