The length of the support post is 40 ft.
<u>Solution:</u>
Given, the height of the wall is 20 ft; support post forms 30 degree
Refer the attached image
Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and 
is 30 degree (
) and AC is the length of the post.
To find: The length of the post (AC)
we know the formula, 
(trigonometric formula)
On substituting the values we get,
The value of sin 30 degree is 0.5
The anwser is 3x-5 yuhhhhhhhhhhhhhhhhh
Answer:
1. Formula is A2 : A9 = COUNT( A2: A9 ) = 8
2. Formula is SUM( A2: A9 ) = 36
3. Formula is B2 : B9 = COUNT( B2: B9) = 8
4. Formula is MAX( C2: C9) = 5
5. Formula is MIN( C4: C8) = 3
6. Formula is SUM( C5 - C6) = 0
7. Formula is AVERAGE( C2: C9) = 4
