Step-1 – Given

Perimeter =22 units, length of each sides are $x, x + 1, 5.$

Step-2 – To determine

We have to find the value of the x for the given triangle.

Step-3 – Calculation

The equation of the perimeter will be,

$x + (x + 1) + 5 = 22$

$\begin{array}{l} x + (x + 1) + 5 = 22 \\ x + x + 1 + 5 = 22 \\ 2 x + 6 = 22 [combine like terms] \\ 2 x + 6 - 6 = 22 - 6 [subtract 6 from each side] \\ 2 x = 16 \\ 2 x \div 2 = 16 \div 2 [divide each side by 2] \\ x = 8 \end{array}$

Hence, the required value of x is 8.
