Answer:

angle 1= 31°

angle 2= 121°

angle 3 =47°

Explanation:

finding 1:

angles in a triangle equal 180°

to find remaining angle add up the angles you know and subtract them from 180

right angle equals 90°

90+59= 149

180-149= 31

finding 2:

angles on a straight line equal 180°

subtract known angle from 180 to find angle

180-59=121

finding 3:

angles in a triangle add up to 180°

to find remaining angle add up the angles you know and subtract them from 180

12+121=133

180-133= 47
