Question

Please help me please

Answer 1

16.53

Explanation:

Start by finding the length of the line in the center. I will call this line a. Using the Pythagorean Theorem with 12.3 as the hypotenuse:

`c^2=a^2+b^2\\a=√(c^2-b^2) \\a=√(12.3^2-5.4^2) \\a=√(122.13) \\a=11.05`

Now that this line is known, x can be found. Once again using the Pythagorean Theorem:

`x^2=a^2+b^2\\x=√(a^2+b^2) \\x=√(12.3^2+11.05^2) \\x=√(273.39) \\x=16.53`
