Answer:
X=14
Explanation:
The question tells us that the triangle is an equilateral triangle, meaning all of its side lengths are equal.
The perimeter of the triangle is all the lengths added together, so we can say this:
Perimeter=3(1.75x-2)
And since the question tells us the perimeter, we can input that into the equation as well.
67.5= 3(1.75x-2)
And now we solve:
67.5= 3(1.75x-2)
Distribute 3 into the parentheses
67.5=5.25x-6
Combine like terms (move -6 to the other side)
67.6+6=5.25x
73.6=5.25x
Divide both sides by 5.25
73.6/5.25=5.25x/5.25
14=x
I hope this helps! Please comment if you have any questions.

Answer:
Step-by-step explanation:
You don't need to memorize all of the square roots. Looking at each square root, find a number close to it that you know -- The square root of five is close to the square root of four, which is 2. The square root of 28 is close to the square root of 25, which is 5. 28 is a slightly bigger than 25, so the square root will be slightly greater than 5.
