Answer:

\sf\boxed{a=6}}}

Step-by-step explanation:

Isolate the term of a from one side of the equation.

14/21=a/9

Use cross products.

\sf{14*9=21*a}

Solve by a.

A=\dfrac{14*9}{21}=\dfrac{126}{21}=\boxed{\sf{6}}

<u>a=6</u>

So, the final answer is a=6.

I hope this helps! Let me know if my answer is wrong or not.

21 + 37 >= 15
58 >= 15

21 + 15 >= 37
36 >= 37

37 + 15 >= 21
52 >= 21

We can see that the second inequality doesn't comply, thus there is not such triangle.</span>
