Answer:
X = 36°, y = 54°, z = 90°
The ratio of the values of ∠x, ∠y, and ∠z = 2:3:5
Let the angles be 2a, 3a, and 5a
∠BOF = ∠AOE = x° = 2a (Alternete angles)
∠EOD = ∠COF = y° = 3a (Alternate angles)
∠AOC = ∠DOB = z° = 5a (Alternete angles)
∵ ∠EOD + ∠DOB + ∠BOF + ∠FOC + ∠COA + ∠AOE = 360°
3a + 5a + 2a + 3a + 5a + 2a = 360°
20a = 360°
a = 360/20 = 18°
∵ x = 2a = 2 * 18 = 36°
y = 3a = 3 * 18 = 54°
z = 5a = 5 * 18 = 90°
Therefore, x = 36° , y = 54° , and z = 90°
