Answer:
x = 13[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio with the 45° angle on lower left and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex]
ain45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{13}{x}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
x = 13[tex]\sqrt{2}[/tex]
