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

B=c-5
c+b=185
so, c+(c-5)=185
2c=190
c=95
b=90
As simple as that.

Answer:</h2>
All we need to do is solve for y.
The answer is <em>A. y = 4x + 11</em>.
Answer:
v² -5v -24
Step-by-step explanation:
(v +3)(v - 8)
FOIL
Front
v x v = v²
Outer
v x -8 = -8v
Inner
3 x v = 3v
Last
3 x -8=-24
put it together in standard form (highest exponent to lowest)
v² - 8v +3v -24
combine like terms
v² -5v -24
Answer:
the answer is x is 3 and y is 6
