The value of y = 12.
Given,
m ∠ABC = 40° and BD is the angle bisector of ∠ABC.
To find the value of y=?
Now, According to the figure,
For value x, (Adjacent angles)
3x - 1 = 34 - 2x
3x + 2x = 34 +1
5x = 35
x = 7
And, For value of y ,
A and C are altitude
3y +6 = 5y - 18
3y - 5y = -18 - 6
-2y = -24
y = 12
Hence, The value of y = 12.
