I would hazard a guess and say it was 10.
For isosceles triangle both legs are the same, 10 cm. The hypotenuse is square root of sum of legs squared, = sqrt (10 squared + 10 squared) = 14.1 cm
The triangle's altitude is 8.7 (8.66025) cm.
With an altitude of 10 units, this triangle's sides each measure 11.55 (11.54701) units.
isosceles acute triangle.
This would be an isosceles triangle.
To have an altitude of 8 cm it could have a base of 12 cm and two equal sides of 10 cm which would satisfy Pythagoras' theorem because an isosceles triangle is in fact two right angle triangles joined together. Area of a triangle = 1/2*base*height Area = 1/2*12*8 = 48 square cm
In a isosceles triangle, the altitude is also a median. If we draw the altitude, then two congruent right triangles are formed, with hypotenuse length of 12m and base length 5 m (10/2). So the length of hypotenuse, by the Pythagorean theorem is h^2 = 12^2 - 5^2 h = √(144 - 25) h = √119 h ≈ 10.9
For isosceles triangle both legs are the same, 10 cm. The hypotenuse is square root of sum of legs squared, = sqrt (10 squared + 10 squared) = 14.1 cm
Let the given area is 10cm. Base of the triangle is 4 cm. altitude of triangle=? Area= 1/2 x Base x altitude 10= 1/2 x 4x altitude 10=2 x altitude 10/2= altitude 5= altitude Hence, altitude of the triangle is 5 cm.
The triangle's altitude is 8.7 (8.66025) cm.
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
With an altitude of 10 units, this triangle's sides each measure 11.55 (11.54701) units.
The dimensions given relate to an isosceles triangle
an isosceles triangle is a triangle with two of its sides equal and one side different such as a triangles sides that measure as 10 cm 10 cm and 7cm, this would be an isosceles triangle as one of the sides is not the same length as the other two, hope this helped :)
