Use Pythagoras' theorem:
82-52 = 39 and the square root of this is 6.244997998 or 6.245 feet in height to 3 d.p.

When can the leg of an isosceles triangle be used as the height of the triangle?
Yes if the isosceles triangle is a right isosceles triangle because that leg opposite the hypotenuse is the height
How do you find height of isosceles triangle if you only know the length of equal sides and the base?
i can
What is the formula for the area of an isosceles triangle?
The are of any triangle is calculated by the formula: Area = 1/2 x Base x Height
You know base and angles how do I find height of isosceles triangle?
Use the sine rule to work out one of the sides. (a/sina = b/sinb = c/sinc) Then as it is an isosceles triangle the perpendicular dropped from the apex will (a) bisect the base and (b) form a right angle with the base. Now you know one side and the hypotenuse of a right-angled triangle and you use Pythagoras (a2 + b2 = c2) to solve the 'other' side of that, which is the height of the isosceles triangle.
Thomas said that scalene isosceles and right triangle have different areas because they look different marlika disagrees and says that if they have the same base and the same height their areas will?
The area of a triangle is half the base times the height, so obviously the areas will be the same if these figures are identical, but I doubt it is possible to have such correspondence between any two of the triangles you mention! Consider mapping a right triangle to an isosceles - I can't keep the altitude constant.
When can one of the two congruent sides of an isosceles triangle can be used as the height of the triangle?
When it's a right triangle and it's sitting on one of the congruent sides.
When can the leg of an isosceles triangle be used as the height of the triangle?
Yes if the isosceles triangle is a right isosceles triangle because that leg opposite the hypotenuse is the height
When can one of the two congruent sides of an isosceles triangle be used as the height of the triangle?
When it has a 90 degree angle and 2 equal angles of 45 degrees
An A-frame tent is in the shape of an isosceles triangle The base of the triangle is 10 ft and the two congruent sides are each 8 ft What is the height?
6.20 feet
How do you find the base and height of an isosceles triangle?
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
What is the circumradius of an isosceles triangle?
To find the circumradius of an isosceles triangle, the formula is:1/8[(a^2/h)+4h]in which h is the height of the triangle and a is the base of the triangle.
The triangle at the right is an isosceles triangle. if?
legs Base and height are equal in langth
A tent is in the shape of an isosceles triangle The base of the triangle is 10 ft and the two congruent sides are each 8 ft What is the height?
Use pythagoras' therom: 82-52 = 39 and the square root of this is 6.244997998 height = 6.245 ft to 3 d.p.
If weRotation of a right angled triangle about its height what shape we will get?
An isosceles, possibly equilateral, triangle
Area of isosceles triangle?
Area of any triangle is: 0.5*base*perpendicular height
If the base of an isosceles triangle is 11 and the perimeter is 39 what is the length of a leg?
If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
Area of isosceles tiangle?
The formula is: Area = base * height. With an isosceles triangle, two of the angles are congruent and their opposite sides are congruent. There is one remaining angle (that will be referred to as the top angle) and its opposite side (the base). You will probably have to drop a perpendicular line from the top angle to the base. This will bisect the base into two equal parts. Also, you now have two congruent right triangles. It depends on what you know with this triangle in order to find its height and/or base. However, use the Pythagorean Theorem and I'm sure you can work it out.
