Find each angle measure

11. = 132. 12. = 27. 13 = 59

Step-by-step explanation:

For the first one it adds up to a straight angle, which is 180. So to get that we do 180 - 48 which is 132. For the second it adds up to a right angle, 90 - 43 is the equation you do. and for the last one, the two angles are congruent so you just subtract 90 - 31, like the last one

12.4, 12.387, 12.26, 12.252, 6.241, 6.2, 6.015, 6.009, 1.411, 1.2, 1.056, 1.007, 0.31,   0.13, 0.5, 0.04
