PLS HELP!! this is due today pls help me thank u so much.

23.3

Step-by-step explanation:

Use phyth. Thm.

a^2 + b^2 = c^2

A and B are the side lengths, and C is the hypotenuse. The hypotenuse is across the right angle.

Since you only have one side length and the hypotenuse this what your equation will look like:

30^2 + x^2 = 38^2

900 + x^ = 1444

544 = x^2

x = roughly 23.3

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
