Answer:
<h2>x = 15</h2>Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x
Using Pythagoras theorem we have
a² = b² + c²
where
a is the hypotenuse
b and c are the other two sides
So we have
We have the final answer as
<h3>x = 15</h3>Hope this helps you
The value of x is 3.
Solution:
Length of the top rectangle = x ft
Width of the top rectangle = x ft
Height of the top rectangle = 3x ft
Volume of the top rectangle
Volume of the top rectangle cubic feet
Length of the bottom rectangle = ft
Width of the bottom rectangle = ft
Height of the bottom rectangle = 0.5 ft
Volume of the bottom rectangle
Volume of the bottom rectangle cubic feet
Total concrete for both pieces = 90 cubic feet.
Volume of top + volume of bottom = 90 cubic feet
Solve by factoring.
x = 3,
Solve using quadratic formula,
Ignore the complex roots.
The value of x is 3.
