Hi there, so we know that all triangles add up to 180 degrees so we will take 38 and add it with 25 to get 63 then we subtract 180 by 63 to get 117 which is your awnser!! I mean I might be wrong but I’m probably right. I hope this helps!! Have a great morning, night, or day, Whatever it is for you!
