If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
If the perimeter is 60 feet on a triangle with sides in the ratio of 3 4 5 what is the length of the longest side?
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 you solve 5x equals 25?
5x = 25Divide both sides by 5:x = 5
What polygon has the same number of diagonals as it has sides?
In short: The Pentagon In Long: The formula for the number of diagonals is (x*(x-3))/2 So if you make that equal to x you get 5. (x(x-3))/2=x (x^2-3x)/2=x x^2-3x=2x x^2-5x=0 x=0 or x-5=0 x=0 or x=5 x=5 Because there is no polygon with 0 sides and the pentagon is defined as a polygon with 5 sides, the pentagon is the only regular polygon with the same amount of diagonals as it has sides.
How do you solve 5x plus 1 equals 21?
If: 5x+1 = 21 Then: 5x = 21-1 => 5x = 20 Divide both sides by 5 and so x = 4
What is the perimeter of a pentagon whose length is x plus 4?
A pentagon has five sides. If each side is x + 4, then multiply that by 5 to get the perimeter, which is the length of all the sides put together. 5(x+4) Distributive property: 5x + 20 Answer: 5x+ 20
Find the perimeter of the triangle with sides of length x 5x and 6x-3?
Find the perimeter of the triangle with sides of length x, 5x and 6-3x?
What is the perimeter of a regular pentagon with a side whose length is x plus 4?
5x + 20
How do you find the perimeter of a triangle with sides like 2x and 5x and 6x?
To find the perimeter of a triangle you have to add up all the sides. So to find the perimeter of this triangle you just add 2x+5x+6x=13x. To find the actual perimeter you would have to know what x equals
What is the perimeter of a square with a side of 5x?
4 * 5x = 20x
Write a polynomial for the perimeter?
The perimeter of a polygon is simply the sum of the lengths of its sides. There is no polynomial that expresses that for all polygons, but the perimeter of a rectangle is P=2(L+H) where P is the perimeter, L is the length, and H is the height.
How much degrees is a pentagon?
The sum of internal angles of a shape is given by the equation 180(n-2) where n is the number of sides. For a pentagon, which has 5 sides, this would be 180x3 = 540. The sum of external angles of a shape is given by (180-(x/n))n where n is the number of sides and x is the sum of internal angles. For a pentagon, this would be 5x(180-540/5) = 360
How do you find perimeter when one side is 4x second side is x?
You have not said how many sides the figure has, I am assuming it is a rectangle so the perimeter is twice the sum of adjacent sides ie 5x by 2 = 10x. Make it easier for those who answer by stating your question fully and accurately.
If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
What is the perimeter of a pentgon?
If you know one side you know the perimeter which is the whole thing around it.
The perimeter of a hexagon is 91cm if one side has a length of 5x plus 3 then what does x equal?
One side has lenght 5x+3 and there are 6 sides. so the perimeter is 30x+18 and we are told that equal 91 30x+18=91 30x=91-18=73 x=73/30 cm or about 2.43 cm
If an equilateral nonagon has one side of 5x-3 what is its perimeter?
