Part 4) In the right triangle of the figure
a) Find the value of x
we know that
[tex]sin(45\°)=\frac{7}{x}[/tex]
[tex]x=\frac{7}{sin(45\°)}[/tex]
Remember that
[tex]sin(45\°)=\frac{\sqrt{2}}{2}[/tex]
substitute

[tex]x=7\sqrt{2}\ units[/tex]
b) Find the value of y
The value of [tex]y=7\ units[/tex] ----> by triangle 45°-90°-45° measures
