The calculated value of x that makes the triangles similar is 9
How to determine the value of x that makes the triangles similar
From the question, we have the following parameters that can be used in our computation:
The triangles
The triangles are similar to one another
So, we have
(5x - 5)/35 = 48/42
This gives
(x - )/7 = 8/7
So, we have
x - 1 = 8
Add 1 to both sides of the equation
x = 9
Hence, the value of x is 9
