Answer:

[tex]a = 17 \sqrt{2} [/tex]

Step-by-step explanation:

To find a we use sine

sin ∅ = opposite / hypotenuse

From the question

a is the hypotenuse

17 is the opposite

Substitute the values into the above formula

That's

[tex] \sin(45) = \frac{17}{a} [/tex]

[tex]a \sin(45) = 17[/tex]

[tex]a = \frac{17}{ \sin(45) } [/tex]

[tex] \sin(45) = \frac{ \sqrt{2} }{2} [/tex]

[tex]a = \frac{17}{ \frac{ \sqrt{2} }{2} } [/tex]

We have the final answer as

[tex]a = 17 \sqrt{2} [/tex]

Hope this helps you
