#1**+2 **

Hi guest!

So first of all, we know that the blank angle of the triangle is \(180-(w+47)^{\circ}\)since, it's a straight line.

We also know that 3 angles of a triangle sum to \(180^{\circ}\)(triangle theorem).

So, we know \(w+w+13+180-w-47=180\)

If we combine like terms and simplify, we get:

\(w+146=180\)

\(\boxed{w=34^\circ}\)

We can check this too: 34+(34+13)+180-34-47=180

I hope this helped you, guest!
