An isosceles triangle has a base of 22 cm and a vertex angle of 36 degrees. Find its perimeter?
If the vertex angle is 36 degrees then the two base angles must be 72 degrees each. An isosceles triangle can be thought of as being two conjoined right angled triangles. So by halving the base we can work out the hypotenuse with the trigonometry ratio for the cosine. cosine = adj/hyp and when rearranged hyp = adj/cosine hyp = 11/cosine 72 degrees = 35.59674775 Perimeter = 35.59674775+35.59674775+22 = 93.1934955 cm
What is the leg of isosceles triangle if the base is 10 and area is 10?
An isosceles triangle is in effect two right angled triangles joined together and in this case they have bases of 5 units and heights of 2 units so use Pythagoras' theorem to find the hypotenuse which will be the length of one of the equal legs of the isosceles triangle:- 52+22 = 29 and the square of this is about 5.385164807 or 5.385 to 3 dp
What is the perimeter of an equilateral triangle with an altitude of 15?
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
How do you find the perimeter of a triangle with perpendicular height?
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
How do you find a perimeter of an isosceles triangle?
Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.
How do you find the perimeter of an isosceles triangle when you only have one side and the base?
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
How do you find the side of an isosceles triangle?
An isosceles triangle has 3 sides 2 of which are equal in length
How do you find perimeter of isosceles triangle with one side?
You cannot since there is insufficient information.
How do you find the perimeter of a triangle when all three sides are given?
If you have the length of each of the three sides of a triangle, you can find the perimeter of (the distance around) the triangle by adding the length of the sides. Their sum will be the perimeter of this geometric shape.
How do you find the perimeter of a scalene triangle?
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
How do you find the volume of a 3D isosceles triangle?
V= area of the triangle x length
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?
How do you find the length of a triangle when perimeter is given?
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
How can you find the perimeter of isosceles triangle?
The answer depends on what information you have but, basically, you need to add together the lengths of the three sides of the triangle.
How do you find the length of a triangle?
Find the perimeter by adding the lengths of the sides
How do you find Ares and perimeter on a tringle?
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
