The top graph is correct because an x=# will create a vertical line at that #
Model it like an equation.
0.75x = 66
x=66/0.75
x=88
Al wears a size 12
5+2x=29
5 (5 more) 2x (two times als shoe size) = 29
The sum of all the angles of any triangle is 180 degrees
--> Therefore the missing angle is:
<u>x = 180 - 60 - 75 = 45</u>
Hope that helps!
