Answer 1

x= 20,1 degrees

Explanation:

The sum of the inner angles of a triangle is 180 degrees

So it must be

3x-11+6x-10+x = 180

added up the terms with x

10x -11-10 = 180

added up the terms without x

10x - 21 = 180

added up (21) in the two members of the equation

10x-21+21 = 180+21

10x = 201

divide the two members by 10

x = 20,1 degrees
