Answer:
∠ ADC = 110°
Step-by-step explanation:
∠ CDE = 90° ( angle between perpendicular lines ) , then
∠ CDB + ∠ BDE = 90°
∠ CDB + 20° = 90° ( subtract 20° from both sides )
∠ CDB = 70°
∠ ADC and ∠ CDB are adjacent angles on a straight line and sum to 180° , so
∠ ADC + ∠ CDB = 180° , that is
∠ ADC + 70° = 180° ( subtract 70° from both sides )
∠ ADC = 110°
Answer:
The answer will be:
b ≥ 10
Step-by-step explanation:
The bracelets cost $2 and the earrings cost $3.
She needs to make at least $60.
She will need to sell more than 10 bracelets.
b = bracelets
e = earrings
2b+3e ≥ 60

Answer:
the total cost of the bike including modifying cost is $24,150
Step-by-step explanation:
⇒ bike cost: $21,000
⇒ 15% of $21,000 is 0.15 x 21,000 = 3,150
⇒ initial + additional cost: $21,000 + $3,150 = $24,150
