Answer:
Step-by-step explanation:
Answer:
t = 5 seconds h = 128 feet
Step-by-step explanation:
The given equation of the object is :
.....1
When it hits the ground,
h(t) = 0
So,

The object will hit the ground in 5 seconds.
Now, put t = 1 s in equation (1).

The object is at a height of 128 ft at 1 second.
∠IJG = ∠FGE (they are corresponding angle)
So, ∠FGE = 50°
Answer:

Step-by-step explanation:
Let the three sides be a, b and c respectively.
Such that:
