ahh bro so theres a straight line right? yeah, so when the other line goes through that line it makes four angles total where they cross, we go one side by one side of the horizontal line. We already see that one side is 72. The straight line is 180 degrees cos it has to be since its straight. so its 180-72, and that gets 108 on the left side. So its basically same on the bottom too, just backwards
