Answer:
x = 40
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
126° is an exterior angle of the triangle, then
x + 2x + 6 = 126
3x + 6 = 126 ( subtract 6 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40

Step-by-step explanation:
if their pay is the same, the equations have to be equal
amelia = jayden
185 +.095x = 311 +.085x
subtract .085x from each side
185 +.095x-.085x = 311 +.085x-.085x
185+.01x = 311
subtract 185 from each side
185-185+.01x = 311-185
.01x = 126
divide by .01
.01x/.01 = 126/.01
x = 12600
