Answer: the model should be 1.75 feet
18-2x=4x is given
18=6x is addition property of equality
3=x is I think division property of equality bc you divided to get x=3
36, 3.6, 0.36, 0.036 is the order
V= 50 degrees
This is because the line on which the angle 70 is at adds up to 180 and it we subtract 70 from the straight angle we have 110 degrees that means the other angle on the other side of the 70 is 110 so if we add 110 and 20 we get 130 and since all angles of a triangle add up to 180 we subtract 130 from 180 and get 50
That is also 21/4 * 8/5 = (21*8)/(4*5) = 168/20 = 8 and 2/5
