A) 5/100 x 420 = 21
21 x 12 x 3= 756
420 x 12 x 3 = 15,120
15,120+756= 15,876
b) 4/100 x 420= $16.8
The measure of BD ≈ 5.36
<u>Step-by-step explanation</u>:
- The side BC = BD+DE+EC.
- The measure of BC = 20 and DE ≈ 9.28
- The angles ∠BD and ∠EC are both equal to 15°
- If the angles are same, then their sides are equal.
Let 'x' be the measure of BD and EC.
BC = x+9.28+x
20 = 9.28 + 2x
2x = 20-9.28
x = 10.72/2
x = 5.36 (approx.)
∴ The measure of BD ≈ 5.36
