Hello! Sorry, this took a minute.
All of the x's are on the same line, and they are equal to 180 degrees.
2x+x+3x+x=180
A straight line equals 180.
Combine like terms.
7x=180
Divide both sides by 7.
25.714... round to 25.7
Now, plug that into the angle that is vertical to 2y. (3x)
3(25.7)= 77.1
So, 3x= 77.1 and 2y= 77.1
Plug that in.
2y=77.1
Divide both sides by 2.
y=38.55
Round that up to 38.6.
"D" is the answer.
I hope this helps!
