How to find the distance between two points on the same longitude

[@abdfatahabdullah1863]

I love Tambuwal Maths Class. It simplifies the whole lesson in the shortest possible time. Well-done.

Thank you

I've got what I've been looking for for years. Thank you, sir

[@uchepromise9669]

Good evening Sir.Pls help me with this question-
A ladder of length 4.5m leans against a vertical wall making an angle of 50° with the horizontal ground. if the bottom of a window is 4m above the ground, what is the distance between the top of the ladder and the bottom of the window? (answer correct to the nearest cm)

Great sir ,watching from India 🇮🇳

wow its amazing

[@thomasrope5155]

it is much easier to considerate that one degree is 60 nm and one second is 1 nm .

[@magdalenaenock1103]

Sorry,,,Why dont you multiply by cos 105 in the formular?

[@tambuwalmathsclass]

Because 105 is a common longitude between the two towns.
And formula for calculating the length of an arc is required.

[@agesinstephen7343]

Because longitude line is a great circle

But sir in some textbooks they us ∅/360*2πRcos∅ please what's the difference( please can u explain using this question P and W are two towns one the Earth's surface on latitude 56N. Their longitude are 25E and 95E respectively. Find the distance PW along their parallel of latitude, correct to nearest km.)

[@sulaimonhammedakinkunmi7754]

Anytime you have a question to measured along parallel of latitude then the formula is what you have stated unlike when it is measured along great circle that the instructor demonstrated.
So, the solution to your question goes thus
95 -25 = 70 angular difference
Then
Distance = 70/360 * 2* 22/7 * 6400* cos 56.
= 4374km

[@sukainaumar-ik8xb]

Is this for jss3 or sss3

[@tambuwalmathsclass]

Sss

[@edehchisom7721]

Help me solve this maths....
Calculate the distance between the needle point of a part of dividers, if the arms are 11cm long and the angle between them is 94°
