Answer:

x = 21

Step-by-step explanation:

SO, angles of a straight line = 180°

You can find out the 'missing angle' on your right simply by substracting 131° from 180° --> 180°-131° = 49° is our missing angle.

Now, angles in a triangle ADD upto 180° therefore,

(2x+11)°+(4x-6)°+49° = 180° --> solve for x

2x+11+4x-6+49 = 180

2x+4x+54 = 180°

6x = 180 - 54

6x = 126

x = 21

Hope this helps!

Answer:

Step-by-step explanation:

alternate interior angles are equal 2x +11=131 2x =131-11 2x =120 x =60 2x+11 = 2(60)+11=120+11=131
