Answer:
5
Step-by-step explanation:
divide the figure as a triangle and a rectangle first.
take away the rectangle part and if you just look at the triangle part,
you can get x using Pythagorean theorem.
Pythagorean theorem is a^2 + b^2 = c^2,
so 3^2 + 4^2 = x^2.
If you calculate it, x should be root 25, which equals 5.
So, the answer is 5.
