The question is asking for angle N. We know from the question that angle N is equal to angle E (Don't think about the scale factor because it only applies to the sides. They're just trying to trick you).
To find angle E: Move numbers to the right side: Combine like terms: Divide both sides by 13: The formula for angle E: Plug in the 8: The angle measure of E is 42. So angle N is automatically 42 too.
To solidify, we can try to use the formula which they give us for angle N:
Let m stand for number of minutes .12m+2=25.04 .12m-2=25.04-2 .12m=23.04 .12m÷.12=23.04÷.12 m=192 The number of minutes is 192 minutes. Hope that helps you!!
