Answer:
- 108
Step-by-step explanation:
Substitute s = - 3 into the expression
- 3 | 15 - (- 3) | + 2(- 3)³
= - 3 | 15 + 3 | + 2(- 27)
= - 3 | 18 | - 54
= - 3 × 18 - 54
= - 54 - 54
= - 108
Answer:
y=2x+4
Step-by-step explanation:
Answer:
∠1=66⁰
∠2=24⁰
∠3=24⁰
∠4=90⁰
Step-by-step explanation:
∠2=∠ADB=24 (ΔADB is isosceles, so ∠ADB=∠ABD)
∠4 =90 (right angle)
∠3=24 (BD bisects ∠ABC, so ∠2=∠3)
∠1+∠2+90=180 (angles in triangle add to 180)
∠1=66
