Answer:
24.46
ahh im so redfaced rn help lol XD
We can use sine to figure this out. Sine is opposite over hypotenuse.
So therefore:
sin(45°)=x/24
x=24sin(45)
x=12√2 or about 16.970
Subtract 30, then factor the equation.
... x² = 30
... x² - 30 = 0
... (x -√30)(x +√30) = 0
By the zero product rule, the solutions are values of x that make a factor be zero.
... x - √30 = 0 . . . . the first factor is zero
... x = √30
... x + √30 = 0 . . . . the second factor is zero
... x = -√30
The solutions are . . .
... x = ±√30 . . . . . matches your 3rd choice
