I need someone to help me out with the solution to these questions.
1. What is the difference in the local time between two places in latitude 55 N if they are located at longitudes 8 W and 18 E respectively.
2. The earth rotates on its own axis once in 24 hrs . What is the speed in km/hr of a place whose latitude is 30
S (take 2.pie.r to be 40000).
3. A regular polygon of 2k + 1 sides has 140 degree as the size of each interior angle. Find k.

1.18+8=26
1degree =4 mins
26degree =104 mins
2.30/360*40000=10000/3
Speed=distance/time
10000/3/24=2500/18km/hr
3.Let n=2k+1
(2n-4)90=140n
180n-360=140n
N=9
2k+1=9
K=4

A+B=200,000 Let A=5% B=7% A=200000-B 5%(200000-B)+7%(B)=11600 1000000-5B+7B=1160000 2B=160000 B=80000 So the 5% is 200,000-80000 =120000

LOC1:
let me try:
cos2y( sec2y + sec2y x tan2y)
=cos2y (2sec2y x tan2y)
recall that sec=1/cos
=cos2y (2/cos2y x tan2y)
=cos2y (2tan2y/cos2y)
=2tan2y [2tan. Square. Y]

let cos 2y be p
Cos2y(1/cos2y+1/cos2y*sin/cos2y)
P(1/p+1/p*sin/p)
P(1/p+sin/p^2)
P(p+sin/p^2)
P+sin/p
