Confused on the final answer when finding the angle

How did you find 1800 as a common denominator

[MargretMilimo-uy]

Hi sir, when i calculated 9000-77650 it gave me -68650 am confused

[marthalubemba]

Sir how do you know that it's cosine

[BarbraChileshe-sh]

I'm confused on the area we found it was 5364 but on the short distance on area you wrote 5360 why is that am confused but on the whole explanation it was clear

[kaylah-ekmn]

I'm confused where we did we get 2bc 🙃

[ennychingaila]

How came it's 119.9 ad not 119 coz they have not given us if it's to how many decimal figures ad the rules of the first page says if degree of accuracy is not specified in the question ad if the answer is not exact give the answer in three significant figures. Or give in degrees to one decimal place

[WendyAfreh-uglt]

Please why have you put something on the A and what is the name for that

[SharonMwenya-ifhn]

Sorry but I never understood how u found area coz ...
