1. Average Speed is distance divided by time. So 363 divided by 165 is 2.2
2. For number 2 I am not sure if there is a missing piece to your question but the car has travelled 72 miles in 220 minutes

√10 √13 √17
Step-by-step explanation:
√10 is the smallest value, √13 is the middle value, and √17 is the largest value.
Answer:
See below ~
Step-by-step explanation:
Identities :
- cot x = cos x / sin x
- sin²x + cos²x = 1
Changing the Left Hand Side (LHS) :
- 1/cot x + cotx
- 1/(cos x / sin x) + cos x / sin x
- sin x / cos x + cos x / sin x
- Take (sin x)(cos x) as the LCM (Least Common Multiple)
- sin x (sin x) + cos x (cos x) / (sin x) (cos x)
- sin²x + cos²x / cos x sin x
- 1/cos x sin x
- Equal to the RHS
Answer:
x ≈ 58.0°
Step-by-step explanation:
Since the triangle is right use the cosine ratio to solve for x
cos x° = 
= 
, thus
x = 
( ) ≈ 58.0°
