Answer:
The total number of cupcakes ordered=216
Step-by-step explanation:
The total number of cupcakes ordered that the baker completed can be expressed as;
C=P×t
where;
C=Total number of completed order of cupcakes
P=percentage of order completed
t=total number of ordered cupcakes
In our case;
C=81
P=37.5%
t=t
replacing in the above expression;
81=37.5%×t
(37.5/100)×t=81
t=81×100/37.5
t=216
The total number of cupcakes ordered=216

Step-by-step explanation:
1st angle = 2x
2nd angle = x
3rd angle = x - 8
Sum of the angles in a triangle = 180°
1st + 2nd + 3rd = 180°
2x + x + x - 8 = 180°
4x - 8 = 180°
4x = 188
x = 47°
Now substitute
1st angle = 2x = 2(47) = 94°
2nd angle = x = 47°
3rd angle = x - 8 = 47 - 8 = 39
Check: 94 + 47 + 39 = 180°
