54 stakes. 12" in a foot, 12x36 = 432, 432/8 = 54

Not much more to say about this. Just multiply the integer by the coefficient.
Answer:
3x+30= 116° 2x=64°
Step-by-step explanation:
the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this
5x+20=180
5x=160
x=32
sub x into the angle equations
3(32)+20=116
2(32)=64
