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
