If △ABC∼△KJL

, find the value of x

in one triangle ABC it has 4x-1 and x+5 and on the other triangle it has 12 and 20

If the triangles △ABC and △KJL are similar, then their corresponding sides are proportional.

We can set up the following ratio:

(4x - 1) / 12 = (x + 5) / 20

Cross-multiplying, we get:

20(4x - 1) = 12(x + 5)

80x - 20 = 12x + 60

Simplifying, we have:

80x - 12x = 60 + 20

68x = 80

Dividing both sides by 68, we find:

x = 80 / 68

x = 1.176

Therefore, the value of x is approximately 1.176.
