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

=2</span><span>(square root)-7
hope this helps</span>
Cody because 18 out of 20 is %90 and 24 out of 30 is %80
Answer:
yes 67 is a prime number because has only 2 divisors
Step-by-step explanation:
Step-by-step explanation:
given,
point = ( -10, -8 ) and ( -8, -16 )
we know,
slope = y2 - y1 / x2 - x1
x1 , y1 = (-10 , -8 )
x2 , y2 = ( -8, -16 )
after inserting the values we got,
→ -16 - (-8 ) / -8 - (-10)
→ -8/2 → -4
therefore, slope of line is -4.
hope this answer helps you dear...take care and may this answer helps you dear!.
