Answer:
5 √ 10 + 2 √ 5 ft high
Step-by-step explanation:Explanation:
Let h be the height to which latter of length of 20 ft reach then using Sine formula in right triangle with hypotenuse 20 & vertical leg h & opposite acute angle 0 = 72∘ sin θ =h 20 sin 72∘= h 20

Answer:
y=3
Step-by-step explanation:
8x=6y
x/y=6/8
x/y=2/3
so y=3
First do 10x7 =70
Since there’s 4 sides with this measure mentally do 70x8=560
560
10x8.7=87
87+560=647
647sq feet
