Answer:
[tex]x=3[/tex]
Step-by-step explanation:
The hypotenuses are equal in length of both triangles.
[tex]13=4x+1[/tex]
[tex]13-1=4x[/tex]
[tex]12=4x[/tex]
[tex]12/4=x[/tex]
[tex]3=x[/tex]
x = 3
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
