The values x = 19°: y = 4°: DFE = 56°
Finding y:
9y = 36°: This equation represents the relationship between angle B and angle D. Since alternate interior angles are equal, we have B = D = 92°.
Solving for y: Divide both sides by 9: y = 4°.
Finding x:
5x - 7 = 88°: This equation represents the relationship between angle A and angle F. Since corresponding angles are equal, we have A = F = 36°.
Solving for x: Add 7 to both sides: 5x = 95°.
Divide both sides by 5: x = 19°.
Finding LDFE:
Angle sum property: The sum of the angles in a triangle is 180°.
Apply the property: LDFE + 92° + (5x - 7) = 180°.
Substitute x value: LDFE + 92° + (5 * 19° - 7) = 180°.
Simplify and solve: LDFE + 92° + 90° = 180°. LDFE = 56°.
Therefore:
x = 19°
y = 4°
DFE = 56°
