Answer:
x = 18, y = 45
Step-by-step explanation:
4x - 7 + a = 180 (linear pair)
But, a = 6x + 7 (alternate interior angles)
=> 4x - 7 + 6x + 7 = 180
=> 10x = 180
=> x = 18
Now, 3y - 20 = 6x + 7 (vertically opposite angles)
=> 3y - 20 = 6(18) + 7
=> 3y = 108 + 7 + 20
=> 3y = 135
=> y = 45
Hope it helps :)

Answer:
Step-by-step explanation:
The question in text and on the picture are different.
Going by picture.
When stating the congruence, it is important to stick to right order of vertices.
The first triangle is ΔCBA
<u>Corresponding angles are:</u>
- ∠C ≅ ∠D, ∠B ≅ ∠E, ∠A ≅ ∠ F
<u>Therefore the second triangle is:</u>
