In ∆pqr, the sum of the measures of ∠p and ∠q is 59o. what is the measure of ∠r?

All triangles are 180 degrees.

1) 59 + 59 = 118
2) 180 - 118 = 62
Therefore,

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
