 In this video we provide the solution to question number four from the practice final exam for math 1060 We're given the angle theta equals 280 degrees and we're asked to convert this degree measurement into radians To convert a degree measure into radians. We multiply our degree measure by pi over 180 degrees So 180 degrees should be on the bottom so that the degree measure cancels out and we're left only with radians Since 280 and 180 are both Divisible by 10 we can see that because the last digit is zero we can cancel out the factor of 10 and very quickly get 28 pi over 18 right here. We do want to simplify this fraction a little bit more 28 and 18 are both even numbers so they're both divisible by 2 28 is 2 times 14 so we get 14 pi over 18, which is 2 times 9, which is 9 there so 14 pi over 14 pi over 9 would be our radian measure, which gives us choice E
