What is the length of the altitude of the equilateral triangle below

E 4√3

Step-by-step explanation:

there are so many way you can use, i show you two if them

1. using phytagoras theorem

a² = 8² - 4²

a² = 64 - 16

a² = 48

a =√48

a = √16 x √3

a = 4√3

2. Using sinus trigonometry

sin x = opp/hyp

sin 60° = a/8

(√3)/2 = a/8

a = 8 x (√3)/2

a = 4√3

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
