Answer:
Explanation:
solve using alternate angles.
the alternate angle to X = 40.
The corner beside 80, is on a straight line adding up to 180 which means that corner is 100.
100+40 =140
180- 140 = 40.
40 is alternative to Z
Z= 40
finally 40 + 40 = 80
Angled in Triangles add up to 180.
y = 100
(ps, if not correct I am sorry, you have drawn out the shape as a square confusing it.)
