Question

The altitude of an equilateral triangle having the length of its side 10cm is ..


​

Answer 1

The height of equilateral triangle =

(10/2)^2+h^2=10^2

25+h2=100

h^2=75

h=5rt3

Answer 2

Answer:

the altitude of the triangle whose side is equal to 10 cm and the triangle is equilateral triangle will be 5√3cm

Explanation:

we can apply Pythagorean theorem to find the value of AD. According to the Pythagorean theorem (Hypotenuse)2=(Perpendicular)2+(Base)2. Hence, the length of the altitude of the triangle whose side is equal to 10 cm and the triangle is equilateral triangle will be 5√3cm
