3x + 4x + 5x = 60 feet
12x = 60
x = 5
The longest side is 5x therefore it is 25 feet. That means that the other sides are 4x (20 feet) and 3x (15 feet).
25 + 20 + 15 = 60

How do i find the Ratio of the shortest to the longest side of a triangle?
You divide the length of the shortest side by the length of the longest side.
What is the ratio of the length of a side of an equilateral triangle to its perimeter?
Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified. Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.
What does sin in maths mean?
sin issinusIn a triangle with a 90 degrees angle, the sinus of an angle is defined as the ratio between the lenghts of the side at the opposite of the angle, and thehypothenuse, the longest side.sin (alpha) = opposite length / hypothenuse length.
The sides of a triangle are in a ratio 5 12 13 What is the length of each side if the perimeter of the triangle is 15in?
2.5ins, 6ins and 6.5ins respectively.The perimeter of a 5-12-13 triangle would be 30 in.The shortest side is 5/30 = 1/6 of the perimeter, the middle side is 12/30 = 2/5 and the biggest is 13/30.So, for the triangle with perimeter 15 inches, the smallest side is 1/6*15 = 2.5 inches.The middle side is 2/5*15 = 6 inches and the biggest side is 13/30*15 = 6.5 inches.
What could be the ratio of the length of of the longer leg of a 30 60 90 triangle to the length of its hypotenuse?
In a 30° 60° 90° triangle, the ratio (long leg)/hypotenuse = sqrt(3)/2 ~ 0.866The ratio (short leg)/hypotenuse = 1/2 = 0.5

How do you 'find the ratio of its length to its perimeter?
Here's how to do that: 1). Find its length. 2). Find its perimeter. 3). Divide (its length) by (its perimeter). The quotient is the ratio of its length to its perimeter.
What does the sine of an angle tell us?
In a right-angled triangle, the sine of one of the smaller angles is the ratio of the length of the opposite side to the length of the longest side.
If a rectangle has a perimeter of 70 feet what is the 4 to 5 length to width ratio?
If the length to width ratio is 4 to 5 then the length to width ratio is 4 to 5no matter what the perimeter. If the perimeter is 70 feet then the sides are 15.555... and 19.444... feet respectively.
What is the Ratio of rectangle 18cm length 84cm perimeter to 15cm length 77cm perimeter?
1:1.23
A triangle with a perimeter of 18inches has one 8inch side find the length of each of the remaining two sides if their ratio is 2 to 5?
the answer is 2 and 5
What can be the ratio of the length of the longer leg of a 30-60-90 triangle?
the ratios in such a triangle are 1:2:sqrt(3) so the longest length is opposite the 90 degree angle and is twice as large as the length opposite the 30 degree angle
HOW do you find the similar ratio of a triangle?
Divide the length of a side of one triangle by the length of the corresponding side of the other triangle.
What can be concluded about a rectangles width if the ratio of length to perimeter is 1 to 3?
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
What is the ratio of the perimeter of a square to the length of its side?
4 to 1.
