Gabe drops a hammer from an apartment that is 30 meters above the ground. The height of the hammer in meters, h, after t seconds
is modeled by the function below. h(t)=-t^2-2t+30
Find the approximate number of seconds it will take for the hammer to hit the ground. Round your answer to the nearest whole number.
A. 0
B. 5
C. 10
D. 30
Let x-----> the measure of the angle formed by the wooden fence and grass
we know that in a right triangle tan x=opposite side angle x/adjacent side angle x opposite side angle x=13 ft adjacent side angle x=21 ft so tan x=13/21x=arc tan (13/21)-----> x=31.76°------> x=32°
