Question is find the values of x and y in the diagram.

Answer 1

Because the two angles on the right add to 180 degrees, we can create this system:


`(2x + 25) + y = 180`

We can also prove that
`3x = 2x + 25`, which, when solved, shows that
`x = 25`.

When plugged in to the original equation, we find that y = 105 degrees.
