The answer is Vertical angles are equal.
Answer:
∠A = 120°
∠B = 60°
Step-by-step explanation:
Since, ∠A and ∠B form a linear pair.
Therefore,
∠A + ∠B = 180°.....(1)
It is given that:
∠A = 2∠B..... (2)
From equations (1) & (2)
2∠B + ∠B = 180°
3∠B = 180°
∠B = 180°/3
∠B = 60°
So, ∠A = 2∠B = 2*60°
∠A = 120°
Time for the whole journey;
Time=
![\frac{Distance}{Speed}](https://tex.z-dn.net/?f=%20%5Cfrac%7BDistance%7D%7BSpeed%7D%20)
t=
![\frac{440}{55} hours](https://tex.z-dn.net/?f=%20%5Cfrac%7B440%7D%7B55%7D%20hours)
t= 8 hrs
In driving 275 miles, you take,
t=Distance/speed
t=
![\frac{275}{55}](https://tex.z-dn.net/?f=%20%5Cfrac%7B275%7D%7B55%7D%20)
t= 5 hours
The remaining traveling time is;
8-5
= 3 hours
