Question

Find the value of X In the triangle below

Answer 1

First check attached image

By Pythagoras theorem,

`ac^(2) = {bc^(2) + ab^(2) }`

`→13^(2) = {x^(2) + 12^(2) }`

`→13^(2) = {x^(2) + 144}`

`→169 = x^(2) + 144`

`→169 - 144 = x^(2)`

`→25 = x^(2)`

`→ √(25) = x`

`→5 = x`

Therefore, value of x is 5

Answer 2

x = 5.

Pythagorus Theorem:
c^2 = b^2 + a^2
(13)^2 = (12)^2 + a^2
a = sqrt((13)^2 - (12)^2))
a = 5
