Question

Find the value of X for the triangle (Show all work, triangle and equations in picture)

Answer 1

Answer:

$x=5$

Step-by-step explanation:

The perimeter of a figure is the sum of all its sides.

The sides are x, (x+3), and (2x). The perimeter is 23, so the sum of the expression equates to 23. Thus:

$x+(x+3)+(2x)=23$

Combine like terms:

$4x+3=23$

Subtract 3 from both sides:

$4x=20$

Divide both sides by 4:"

$x=5$

And we're done!
