HELP ME PLEASE GUYS Write and solve an equation based on the relationship between the angles in the diagram below to find the value of a.

Answer:
a = 104
Step-by-step explanation:
The sum of the angles round a point is 360°
Sum the 4 angles and equate to 360, that is
126 + a + 26 + a = 360, that is
2a + 152 = 360 ( subtract 152 from 360 )
2a = 208 ( divide both sides by 2 )
a = 104
