The length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is <em>approximately </em>25.88 feet.
The ladder forms a right triangle as it lies against the wall as shown in the image below.
<em><u>Thus:</u></em>
x = length of the ladder (hypothenuse)
Reference angle 
25 ft = Opposite
Apply SOH:
<em>Thus</em>,


Therefore, the length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is <em>approximately </em>25.88 feet.

Answer:
a) The required sample size n= 55011,57025
b) The sample size is not practical, because that size is extremely large and would be very costly to collect, normally the size have to be significant but no to large to avoid cost unnecessary
Step-by-step explanation:
Range

⇒ 0,99
Sample size can be determinate using equation:
Using confidence level desired 99%
= 2,58
Table used :
<em>Confidence
</em>
<em> 90 % 1,60</em>
<em> 95 % 1,96</em>
<em> </em><em> 99 % 2,58</em>
<em> 99,9 % 3,291</em>
So replacing:

She can arrange them in the following;
1 row of 36
2 rows of 18 (doesnt count because it says other and this has already been mentioned)
3 rows of 12
4 rows of 9 (doesnt count because it says other and this has already been mentioned)
6 rows of 6
Random samples can provide more information on a population of people or things.
Hope I could be of help :)
