Answer:
B) x=3
Step-by-step explanation:
because the 2 angles (that are not the right angle) are both marked with one arc mark, you can assume they are the same angle
therefore, this is a 45-45-90 triangle
there are special properties of 45-45-90 triangles (shown in attatchment below)
with formula can conclude that:
3[tex]\sqrt{2}[/tex]=x[tex]\sqrt{2}[/tex]
divide both sides by [tex]\sqrt{2}[/tex]
3=x
x=3
hope this helps
