Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) What is the length of LN?
To find out the length LN subtract the coordinate of L from the coordinate of N
so

Part 2) What is the length of MN?
To find out the length MN subtract the coordinate of M from the coordinate of N
so

Answer: 2:45
Step-by-step explanation: You add 30 minutes to 1:00, which is 1:30. Next, add 45 to 1:30, which is 2:15. Then, add 30 to 2:15 and you get 2:45!

Frank -----------------------------------------------Base
Frank - Base = 400 ft
Base- Top statue = 360 feet
Angle of elevation =Angle Top-Franck-Base, let it be angle Ф
tan (Ф) = 360/400 = 0.9
arc tan (0.9) = tan⁻¹(0.9) = 41.98 ,
Ten angle of elevation Ф ≈ 42°
