Question

PLZ EXPLAIN HOW TO DO THIS

Answer 1

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!
