Question

Find the missing measures. Given: ABC is a right triangle.



BC = 5, AC = 20, AB = ?

Answer 1

use the pythagoras theorem

AC^2 = AB^2 + BC^2
plug in values of BC and AC and solve for AB

Answer 2

ask if you need further help

Answer 3

18 sqrtof 2?

Answer 4

wait no it would be 5 sqrt 13

Answer 5

20^2 = 5^2 + AB^2
AB^2 = 400 - 25 = 375
AB = sqrt375

Answer 6

375 = 3*5*5*5
= 15 *25

Answer 7

sqrt375 = 15sqrt5

Answer 8

sorry its 5 sqrt15 !!!

Answer 9

my bad logic..

sqrt 375 = sqrt25 * sqrt 15
= 5 * sqrt15

Answer 10

agreed?

Answer 11

agreed!

Answer 12

lol - good!
