Answer:
5.0 ft - 5.6 ft
Step-by-step explanation:
Given that the structure is to be made using two 12 foot boards, then we expect the total perimeter to be equal to (2*12)= 24 ft.
Using the angle of elevation, 40° and the width of 8 ft then you can apply the formula for tangent of a triangle where ;
Tan α = opposite side length/adjacent length
Tan 40°= h/8
h= 8 tan 40° = 6.71 ft
Applying the cosine of an angle formula to find the length of the sliding side
Cosine β = adjacent length /hypotenuse
Cosine 40°= 8/ sliding side length
sliding side length = 8/cosine 40° =10.44 ft
Checking the perimeter = 10.44 +8+6.71= 25.15 ft
This is more than the total lengths of the boards, so you need to adjust the height as;
24 - 18.44 = 5.56 ft ,thus the height should be less or equal to 5.56 ft
h≤ 5.6 ft

hope this helped!
p.s it would be cool if you gave me brainliest.
Yes because in Mrs. Benson‘s class there are 20 students and in Mrs Tracy’s class there are only 18
Answer:
The family donated $52.50
Step-by-step explanation:
Larry's mom donated $7.50 ($15 ÷ $2=$7.50)
Larry's dad donated $25.00 ($5 x $5=$25.00)
Larry's sister donated $5.00 ($15 - $10=$5.00)
Larry donated $15.00
