(x+2)/6 = 2/5
(x+2)5 = 12 <-- Cross multiply
5x = 6 <-- Transpose the 2.
6/5 = x

Answer:

7.8

Step-by-step explanation:

We can use pythagorean theorem $(a^2+b^2=c^2)$ where a and b are sides of a right triangle and c is the hypotenuse.

$x^2+13.3^2=15.4^2$ .

$x^2=15.4^2-13.3^2\\$

$x^2=237.16-176.89\\x^2=60.27\\x=7.763$

Rounded to the nearest tenth, x = 7.8
