Explanation for Question 19 From the Math (No Calc) Section on the 2017 April Sat
Question 19 says an angle with a measure of seven PI over six radians 2 has a measure of D degrees where zero is less than or equal to 3 D, which is less than 360. 4 What is the value of deep? So to confer radiance to degrees, 5 we need to use this equation that I've written down radians times 180 divided 6 by PI is equal to degrees. So I'm going to plug our radiants into 7 this equation. So seven PI over six times, 8 180 go for PI is equal to D the 9 PIs cancel out here. So we know that D is equal to seven times 10 180 divided by six, 11 and that's just equal to 210, 12 which is our final answer.
