Answer:
140°
Step-by-step explanation:
<3 = 40 because they are vertical angles
<3 +<4 = 180 because they are same side interior angles
40 + <4 = 180
Subtract 40 from each side
40-40 + <4 = 180-40
<4 = 140
Step-by-step explanation:
Given that,
The function that shows the height of a baseball after t seconds is given by :
....(1)
Part (A).
When the baseball hits the ground,
H(t) = 0
So,

After 5 seconds the baseball will hit the ground.
Pat (B)
For maximum height, put dH/dt = 0
So,

Put t = 2.34 s in equation (1).

Hence, this is the required solution.
