Answer:
76 degrees
Step-by-step explanation:
find angle 5 by subtracting 76 from 180 to get 104 degrees
the find angle 7 by subtracting 104 from 180 to get 76
180-76 =104
180-104=76

Answer:
21.5secs 
Step-by-step explanation:
Given the function that models the height of an object as
h(t) = -16t^2+ 344t
The object hit the ground at h(t) = 0
Substitute
0 =  -16t^2+ 344t
 16t^2 = 344t
16t = 344
t = 344/16
t =  21.5
Hence it takes 21.5secs for the object to hit the ground
