Answer:

x=28

Step-by-step explanation:

So a triangle is 180 degrees in total then you would subtract 40 from 180 because the top angle and leaving you with 140 then divide by 5 because the bottom two getting you 28 then you could just plug in 28 for x on each angle

180-40=140

140/5=28

2(28)=56

56 is angle A

Answer:
