Answer:
x = 80 degree
Step-by-step explanation:
As sum of all angles in a triangle is equal to 180
so:
According to the given figure:
70 + 30 + x = 180
By simplifying
100 + x = 180
x = 180 - 100
x = 80 degree
i hope it will help you!
The sum of the interior angles of a triangle is 180. Add the three measures given and if you get 180 then those can be the interior angles of a triangle.
