Here's the equation:
1459.75 - (359.45 + 125 + 299.35) + 375
1459.75 - 783.8 + 375
1459.75 - 408.8

Step-by-step explanation:
Mean:
a) 1+4+2+1 = 8/4=4
b)1+5+2+1 = 9/4= 2.25 (round to the nearest whole number = 2)
c) 1+5+1+0 = 7/4 = 1.75 (round to the nearest whole number = 2)
d) 1+4+1+0 = 6/4 = 1.5 (round to the nearest whole number = 2)
Answer:
11.25
Step-by-step explanation:
Since AB and CD are parallel, ∠D is congruent to ∠A and ∠C is congruent to ∠B. Therefore the two triangles are similar by the AA postulate. Now, the corresponding sides are in proportion
Since AE ↔ DE and AB ↔ CD
So, AE/CD = AB/CD
AE/5 = 9/4
AE = 9(5)/4
= 45/4 = 11.25
<BAC = <DEC = 30°
<BCA = <DCE = 70°
<CDE (or m<D) = 180° - <DEC - <DCE
<CDE = 180° - 30° - 70°
<CDE = 80°
The number that belongs in the green box is 80
