To help you find the unknown side length of the triangle, I need some additional information about the triangle itself. Specifically, I need:
1. The lengths of the two known sides (if applicable).
2. The angle measures (if you're dealing with an oblique triangle).
3. The type of triangle (e.g., right triangle, scalene, isosceles).
Please provide this information so I can assist you accurately!

To find the unknown side length in a triangle with the angles given (20° and 30°), we can use the Law of Sines, which states:
\[
\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}
\]
where:
- \(a\), \(b\), and \(c\) are the sides opposite angles \(A\), \(B\), and \(C\) respectively.
1. First, determine the third angle \(C\):
\[
C = 180^\circ - A - B = 180^\circ - 20^\circ - 30^\circ = 130^\circ
\]
2. Now, let's denote the sides opposite to these angles:
- Let \(a\) be the side opposite the 20° angle.
- Let \(b\) be the side opposite the 30° angle.
- Let \(c\) be the side opposite the 130° angle.
Assuming you have the lengths of any two sides, we can find the third side. Let's say you have the length of side \(a\) and you want to find side \(b\).
Using the Law of Sines:
\[
\frac{a}{\sin A} = \frac{b}{\sin B}
\]
Rearranging for \(b\):
\[
b = a \cdot \frac{\sin B}{\sin A}
\]
Substituting the values:
\[
b = a \cdot \frac{\sin 30^\circ}{\sin 20^\circ}
\]
Now, we can calculate this if we know the length of side \(a\). Please provide the length of side \(a\) (or any of the sides), and I can help you compute the length of the unknown side.
\[
\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}
\]
where:
- \(a\), \(b\), and \(c\) are the sides opposite angles \(A\), \(B\), and \(C\) respectively.
1. First, determine the third angle \(C\):
\[
C = 180^\circ - A - B = 180^\circ - 20^\circ - 30^\circ = 130^\circ
\]
2. Now, let's denote the sides opposite to these angles:
- Let \(a\) be the side opposite the 20° angle.
- Let \(b\) be the side opposite the 30° angle.
- Let \(c\) be the side opposite the 130° angle.
Assuming you have the lengths of any two sides, we can find the third side. Let's say you have the length of side \(a\) and you want to find side \(b\).
Using the Law of Sines:
\[
\frac{a}{\sin A} = \frac{b}{\sin B}
\]
Rearranging for \(b\):
\[
b = a \cdot \frac{\sin B}{\sin A}
\]
Substituting the values:
\[
b = a \cdot \frac{\sin 30^\circ}{\sin 20^\circ}
\]
Now, we can calculate this if we know the length of side \(a\). Please provide the length of side \(a\) (or any of the sides), and I can help you compute the length of the unknown side.
