Question

the side of an equilateral triangle is 3√3 find the length of its altitude​

Answer 1

Answer:4.5

Step-by-step explanation:

Answer 2

Side of the equilateral triangle is 3√3

then half of its base =3√3/2

And area of the full triangle is √3*3√3/4

=9/4=2.15cm²

then half of its area =1.075cm²

the area of the half triangle is 1/2*3√3/2*h=1.075

h=1.075*4/3√3

h=1.075*4/5.196

h=4.3/5.196

h=0.827559661cm
