Answer:
- Q1. x = 11, y = 5
- Q2. x = 22, y = 123
Step-by-step explanation:
Question 1
B and E are congruent as corresponding angles
- 11x - 4 = 117
- 11x = 121
- x = 11
AB = DE as corresponding sides
- 17y - 8 = 12 + 13y
- 17y - 13y = 12 + 8
- 4y = 20
- y = 5
Question 2
Sum of interior angles = 180
- 2x + 13 + 3x + 57 = 180
- 5x = 180 - 70
- 5x = 110
- x = 22
57 and y make a straight angle
