The first one. <_ means below and >_ means above. <_ and >_ means solid line < and > mean dotted line. i’m learning this in math right now
Let's assume
shorter side as x
so, first side =2x
third side =x+19
now, we can find perimeter of triangle
perimeter of any triangle is
first side + shortest side + third side
so, we get

we are given perimeter=187
so, we can set it to 187
and then solve for x





so,
shortest length is x=42 feet
First side =2x=2*42=84feet
third side =x+19=42+19=61 feet
so, dimensions are
first side is 42 feet
second side is 84 feet
third side is 61 feet................Answer
its -325

hope this helped gooooood luck ;3
Answer:
X = d/f - 1
Step-by-step explanation:
You would Isolate the variable by dividing each side by factors that don't contain the variable. Hope this helps
