X=32
Explanation: X/9-1=4
X/8=4
8x4=32
These two are true:
<span>Area of ABC = a × b × sinC
Area of ABC = × c × b × sinA
</span>
Where do we find the answer from?
The maximum height reached is 2.87 meters
<h3>What is maximum height?</h3>
The maximum height of an object is the highest vertical position along the trajectory of the object.
The given parameters are:
--- the initial velocity
--- the final velocity
--- the acceleration
To calculate the height (s) of the ball, we make use of the following equation of motion:

Substitute known values


Collect like terms

Substitute 9.8 for g


Divide both sides by 19.6

Hence, the maximum height reached is 2.87 meters
