How to check in the triangle abc side ab is 2 cm shorter than side ac while side bc is 1cm longer than ac if the perimeter is 62cm find the lengths of the three sides?

draw it out for ease.
data:
ab + 2 = ac
bc-1 = ac
therefore ab +2 = bc - 1
ab - bc = -3
perimeter is 62. /3 as most values are small difference. average distance is ~21.
ab is smallest, guess it is 19. if so, ac would be 21. bc would be 22. does this add up?
it actually does. i guess there is a mathematical way of doing this other than trial and error like the way i just did it, but i cannot see it right now

What set of lengths can be used to make a triangle?
There are many lengths that can be used to make triangles. Basically take the longest side, add the two shorter sides together, it can be a triangle as long as the 2 shorter sides added together are longer than the longest side.
A triangle has sides of lengths 6 2 and 7 is it a right triangle?
No. For a right angle triangle, the sum of the squares of the shorter sides equals the square of the longer side (the hypotenuse): 22 + 62 = 40 72 = 49
How do you find the perimeter in a parrallelogram?
Add together the lengths of the 4 sides, or you could add the length of one shorter side to one longer side and then double it. e.g. Perimeter of parallelogram = l = b = l = b, or 2(l + b)
What is the ratio between the lengths of the two legs of ab30-60-90 triangle?
The length of the longer leg equals the length of the shorter leg times the square root of three.
What are the lengths of the longer leg and the hypotenuse if the shorter leg is 10 on a 30-60-90 triangle?
The short side will be opposite the 30 degree angle. The longer leg is 10*sqrt(3) = 17.32 and the hypotenuse is 20.
What is true about the lengths of the three sides of a triangle?
For a triangle to exist, the sum of the shorter two sides must be longer than the third side.
What set of lengths can be used to make a triangle?
There are many lengths that can be used to make triangles. Basically take the longest side, add the two shorter sides together, it can be a triangle as long as the 2 shorter sides added together are longer than the longest side.
How do you find the side lengths of a 20-70-90 triangle?
There are an infinite number of different sets of lengths that will do it. You have to start by choosing the length of one side, and when you do that, here's how to find the others: Shorter leg = (longer leg) x 0.364 Shorter leg = (hypotenuse) x 0.342 Longer leg = (shorter leg) x 2.747 Longer leg = (hypotenuse) x 0.94 Hypotenuse = (shorter leg) / 0.342 Hypotenuse = (longer leg) / 0.94
A triangle has sides of lengths 6 2 and 7 is it a right triangle?
No. For a right angle triangle, the sum of the squares of the shorter sides equals the square of the longer side (the hypotenuse): 22 + 62 = 40 72 = 49
Could a triangle has lengths of 4 9 11?
Yes that is possible. To check, you add the two shorter sides, and they should be longer than the longest side.
He length of the longer leg of a right triangle is 3ft more than three times the length of the shorter leg. The length of the hypotenuse is 4ft more than three times the length of the shorter leg. Fin?
The length of the longer leg of a right triangle is 3ftmore than three times the length of the shorter leg. The length of the hypotenuse is 4ftmore than three times the length of the shorter leg. Find the side lengths of the triangle.
A right triangle has one leg three times as long as the other Find a function that models its perimeter P in terms of the length x of the shorter leg?
The perimeter is the sum of all of the sides of the triangle. If the shorter leg is x, the longer leg is 3x. The hypotenuse is then the square root of x^2 + 3x^2, or 2x. Then the perimeter is x + 3x + 2x, simplified, f(x) = 6x.
How do you find the perimeter in a parrallelogram?
Add together the lengths of the 4 sides, or you could add the length of one shorter side to one longer side and then double it. e.g. Perimeter of parallelogram = l = b = l = b, or 2(l + b)
What is the ratio between the lengths of the two legs of ab30-60-90 triangle?
The length of the longer leg equals the length of the shorter leg times the square root of three.
The shorter leg of a 30 -60 -90 triangle is 9.4 feet long Find the perimeter?
Length of longer leg = 9.4 tan 60 = 16.28 feet Length of hypotenuse = 9.4 ÷ cos 60 = 18.8 feet Perimeter of triangle = 9.4 + 16.28 + 18.8 = 44.48 feet
What are the lengths of the longer leg and the hypotenuse if the shorter leg is 10 on a 30-60-90 triangle?
The short side will be opposite the 30 degree angle. The longer leg is 10*sqrt(3) = 17.32 and the hypotenuse is 20.
The hypotenuse of a triangle is 5 feet long The longer of the two legs is one foot longer than the other Find the length of the shorter leg?
The dimensions given are a classic example of Pythagoras' Theorem for finding the lengths of the three sides of a right angled triangle: 52 = 42+32 So the answer your looking for is that the shorter leg is 3 feet long.
