Answer:
A x =30
Step-by-step explanation:
(y+x) and (y-x) make a straight line so they add to 180 degrees
(y+x) + (y-x) = 180
Combine like terms
y+y+x-x=180
2y=180
Divide by 2
2y/2 = 180/2
y= 90
(y+x) and 2x make a straight line so they add to 180 degrees
y+x+2x = 180
Combine like terms
y+3x = 180
Since we know y we can substitute it in
90+3x = 180
Subtract 90 from each side
90-90+3x= 180-90
3x = 90
Divide by 3
3x/3 = 90/3
x= 30

Step-by-step explanation:
the sum of all angles in a triangle is always (ALWAYS !) 180°.
180 = 31 + 35 + x = 66 + x
x = 180 - 66 = 114°
