In a triangle, the sum of the interior angles must be 180°.
So, for a triangle with side lengths of 20° and 30°, the third angle would be:
180° - 20° - 30° = 130°
Now that we have all three angles, we can use trigonometry to find the missing side length using the Law of Sines:
a/sinA = b/sinB = c/sinC
Let's say the unknown side length is represented by 'x'. We can set up the equation:
x/sin20° = b/sin30°
Solving for 'b', we get:
b = x/sin20° * sin30°
Calculate the value of 'b' using the given information.
if there was a triangle with one side length being 20° and the other being 30°, what is the unknown side length?
