Question

Help please, i am struggling on how to solve!

Answer 1

`x=3`

Explanation:

The hypotenuses are equal in length of both triangles.

`13=4x+1`

`13-1=4x`

`12=4x`

`12/4=x`

`3=x`

Answer 2

x = 3

Explanation:

Let's take the congruency of any side of these two triangles.

In boths Δs ,

=> 4x+1 = 13 (Taking this is rather more convenient)

=> 4x = 13-1

=> 4x = 12

Dividing both sides by 4

=> x = 3
