The graphic says find BC and it says BC = 33 feet
Anyway, assuming the ladder is 34 feet, and makes an 82 degree angle,
cosine 82 degrees = adjacent / hypotenuse
adjacent = cosine 82 degrees * hypotenuse
adjacent = 0.13917 * 34
adjacent (or side BC) = 4.73178 feet

height (line AB) = sine (82 degrees) * hypotenuse (34 feet)
height (line AB) = 0.99027 * 34
height (line AB) = 33.67 feet

Nostrana [21]

Answer:

$\sqrt{2}$ - 1

Step-by-step explanation:

h = 20 – 5t2 = 15 -> t = 1

h = 20 – 5t2 = 10 -> t = $\sqrt{2}$

interval $\sqrt{2}$ - 1

The time a basketball player spends in the air when shooting a basket is called the "hang time." the vertical leap l measured i

Marina86 [1]

Dénote l the vertical leap, then the given equation can be written like this:
$l(t)=4t^2\\\text{Since one inch equate 0.0833333 feet then 44 inches equate }\\44\times 0.0833333=3.6feet\\\text{Add to 33 feet like this:}\\33+3.6=36.6feet\\\text{Now we have to solve the equation:}\\4t^2=36.6\\\text{Divide over 4 we get:}\\t^2= \frac{36.6}{4}=9.15\\\text{Take the square root we get:}\\t=\sqrt{9.15}=3$

The hang time equates then 3 seconds
