Answer:

x=30

Step-by-step explanation:

a straight line is 180 degrees so to figure out x you would do 180-151 which equals 29 however if u plug 29 in for x it wouldn't work because (29-1) equals 28 and 151+28 do not equal to 180 degrees so x would equal 30 because (30-1) is 29

Step-by-step explanation:

straight line = 180°

x= 180 - 151 +1

x = 30

missing angle = x -1

= 30 - 1

= 29
