Explanation:

For any triangle, to find the missing side which in this case is x;

add all sides including the x and equate it to 180 ( sum of angles in a triangle is equal to 180, note that)

sooo...

10 + 30 + x = 180

doing the math

40 + x = 180

x = 180 - 40

x = 150°✓

Hope this helps and also you have learnt to solve it.

Good luck.
