Answer:
a=9, c=19
Explanation:
Aight so basically in 30, 60, 90 triangles there is a formula for the sides
the hypotenuse(the longest side)=2a
The tiny side (the smallest side)=a
and the middle child =
![a√(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/zabq3oncuj4f8v3j5i2qj2wm9nx8zogcow.png)
Based on that we see that a is 9
and since c=2a then it's 18
