When doing trigonometric ratios remember SOHCAHTOA
SOH = sin=opposite/hypotenuse CAH= cos = adjacent/hypotenuse
TOA = tan = opposite/adjacent

The answer is A) tanY = 7/4 tanZ = 4/7

A penny fell off the top of the building and hit the sidewalk below 3.1 seconds later how many meters did the penny fall to the

Sedbober [7]

To solve this we are going to use the free distance fallen formula: $d=0.5gt^2$
where
$d$ is the distance
$g$ is the gravity of Earth $9.8m/s^2$
$t$ is the time in seconds

We know from our problem that the penny fell off the top of the building and hit the sidewalk below 3.1 seconds later, so $t=3.1$ . Lets replace the value in our formula:
$d=0.5gt^2$
$d=0.5(9.8)(3.1)^2$
$d=47.089$ meters

We can conclude that the penny fell a distance of 47.098 meters
