Answer:
y = 6
Step-by-step explanation:
First find the value of x
Since given triangles are congruent,
Therefore measures of corresponding sides will be equal.
4x + 1 = 13
4x = 13 - 1
4x = 12
x = 12/4
x = 3
Next,
2x + y = 8x - 2y
y + 2y = 8x - 2x
3 y = 6x
3y = 6*3 (plug x = 3)
3y = 18
y = 18/3
y = 6
