Como sacar el area de un triangulo equilatero

(√3/4)L²

L = largo de un lado

Step-by-step explanation:

largo de un lado (base): L

altura: (L√3)/2

area = base × altura / 2 = [L × (L√3)/2]/2 = (√3/4)L²

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

the two may have that, even a breakdown is probably offered
