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!

It is really simple. The ratio between both the triangles is 7, so you just divide 49 by 7(it gives you 7) to get the value of x. The answer is option (a) 7.
Hope This Helped!
Good Luck!
