Answer:
0
Step-by-step explanation:
63/9=7
7^2=49
49/7=7
7-7=0
The sum of these two angles is 180°, therefore,
138° + (x + 8)° = 180°.
Simplify the left side of the equation.
146° + x = 180°.
Subtract 146 from both sides.
x = 34°
For this, all you need is the velocity formula which is Vf = Vi + at.
Vf = final velocity.
Vi = initial velocity.
a = acceleration
t = time
Vf = Vi + at.
Vf= 0 + (-<span> 9.8 m/sec^</span><span>2) (7s)
</span>
*The 0 says that the original velocity is zero. The - 9.8 m/sec^2 is gravity because there is nothing else acting upon it, and it is negative because it is falling. The 7s is time time.*
All you have to do then, is simplify to get 68.6 m/s which is B.
