Question

find the length of the attitude of an equilateral triangle of side 3 underoot 3cm.​

Answer 1

Answer:

Side of an equilateral ∆ABC= 3√3 cm. Hence, the length of the altitude is 4.5 cm.

Answer 2

Answer:

$\fbox\red{here solutions}$

Given

side of an equilateral triangle

ABC = 3√3cm

AB = BC . AC = 3√3 cm

let AD = h (altitude)

BD = ½ BC ( altitude bisect the base )

BD. ½ . 3√3 = 3√3/2 cm

AB² - AD² + BD²

(3√3)² - (h)² + (3√3/2)²

=> 27 = h² + 27/4

=> h² = 27-27/4

=> h² = (4.27 - 27)/4

=> h² = 108 - 27/4

=> h² = 81/7

=> h = √81/4

=> h = 9/2

h = 4.5 cm

games the length of the altitude h is 4.5 CM
