Answer:

x = 19.9

Explanation:

These kinds of problems have a specific formula.

Formula: outside (whole) = outside (whole)

We could substitute our variables into this.

For the first line, our outside segment is b and the whole thing is a + b

For the second line, our outside segment is x, and the whole thing is x.


b (a+b) = x(x)\\11 (25+11) = x^2\\11 (36) = x^2\\396 = x^2\\\\x=√(396)

The
√(396) = 19.8997487421

Rounding to the nearest tenth, your answer is 19.9
