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:length = 9 width = 3
Step-by-step explanation:
length =3x
width = x
perimeter = 24 = 3x + x +3x + x = 8x
8x = 24 therefore x = 3
so length = 3(3) = 9 width = 3
so perimeter = 3+9+3+9 = 24
You can not simplify 7/10 because 7 os only on 1 and 7s times table.
These are similar triangles therefore Angle E corresponds to Angle Q - therefore 90 degrees
