Answer:

Step-by-step explanation:

From the given figure and the information, using trigonometry,

[tex]\frac{x}{7}=tan45^{{\circ}}[/tex]

⇒[tex]\frac{x}{7}=1[/tex]

⇒[tex]x=7[/tex]

Also, [tex]\frac{x}{y}=sin45^{{\circ}}[/tex]

⇒[tex]\frac{7}{y}=\frac{1}{\sqrt{2}}[/tex]

⇒[tex]y=7\sqrt{2}[/tex]

⇒[tex]y=9.9[/tex]

Thus, the values of x and y are 7 and 9.9 respectively.
