Answer:

9 [tex]\sqrt{2}[/tex]

Step-by-step explanation:

To find the answer of this equation, you would use the law of sine

so... (18)/sin(90)= (x)/sin(45)

to find for the length of one side simply isolate for x.

Because sin(90) equals 1, you just have to multiply 18 by sin(45) which equals [tex]\sqrt{2}[/tex]/2

so x= 9[tex]\sqrt{2}[/tex]
