I can’t remember how to answer this. I need to find x. Can someone answer this and tell me how to do it?

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
