Given data:
Base of the sale = 12 feet
Height = 16 feet
Finfing the value of x,
The triangle is a right angle triangle , so by using the Pythagorean Theorem
[tex]\text{Hypotenues}^2=Perepndicular^2+Base^2[/tex]
Here, Hypotenues = x
Perpendicular = 16
Base = 12
[tex]\begin{gathered} x^2=16^2+12^2 \\ x^2=256+144 \\ x^2=400 \end{gathered}[/tex][tex]\begin{gathered} x=\sqrt[]{400} \\ x=20 \end{gathered}[/tex]
Thus, the value of x is 20
