Answer:
AO bisects BAC - Needed
AO is perpendicular to BC - Needed
Point O is the midpoint of BC - Not needed
AO is an altitude - Not needed
Step-by-step explanation:
In ΔAOB,
- <BOA = 90° (since AO is perpendicular to BC
)
- <BAO = <BAC (since AO bisects BAC)
In ΔAOC,
- <COA = 90° (since AO is perpendicular to BC
)
- <CAO = <BAC (since AO bisects BAC)
In ΔAOB and ΔAOC,
- <BOA = <COA (since both are 90°)
- <BAO = CAO (since AO bisects BAC)
- AO=AO
So, we can conclude ΔAOB ≅ ΔAOC (<em>ASA property</em>) and hence the base angles <ABO and < ACO of the isosceles triangle ABC are also congruent.
Answer:
5/6
Step-by-step explanation:
3p - 2 = 2p/5 + p - 2/3
3p - p - 2p/5 = 2 - 2/3
2p - 2p/5 = (6 - 2)/3
(10p - 2p) / 5 = 4/3
8p = 4/3 * 5
8p = 20/3
p = 20/24
= 10/12
=5/6
Answer:
no telling.
Step-by-step explanation:
B = √(14² - 9²) = √(196-81) = √115 ≈ 10.7 units
This is 12,000 / 125 minutes = 96 minutes
Answer is a. 1 hour 36 minutes.
