This is where your plan went wrong.

m?B = 45
You need to tell us which two sides this angle separates. Calling it "angle B" means nothing.

No... My daughter is struggling with this question and was hoping for some help from the math pros on this board.
Seriously, what I said.
IF RIGHT TRIANGLE
Sin (angle) = opp/hyp
Cos (Angle) = adjacent/hyp
Tan (angle) = opposite/adjacent
IF NOT RIGHT TRIANGLE USE ONE OF THESE EQUATIONS

All of the above

It's not a right triangle because the angle is 45. If it were it would be an isolese and 24^2+24^2 doesn't equal 30^2. Use b^2=a^2+c^2-2acCosB. Solve for b.

Use law of cosines
b^2 = a^2 + c^2 -2ac*cos B
b^2 = a^2 + c^2 -2ac*cos B

b^2 = 576 + 900 - 1440 * (sqrt 2)/2
Now just solve but be carefully with order of operations
