So I am not asking for any help, on the question, I figured it out and got the right ans. My problem is with the wording.
Question: The points A,B and C lie on Horizontal ground and are such AB=19m, BC=16m and CA=21m
a) calculate the size of angle ACB
The part I have underlined is the bit that through, a bit confusing mainly because I can't really picture it, dose it mean that is lie in the horizontal plane, or something like that. The only way I was able to workout that, I had to use the cosine rule was because it ask me to calculate the size of angle ACB. So basically I made a assumption, which is not good, when trying to figure out maths.
Could someone help me out with the wording of the question, to me its slightly misleading.
Thanks in advance; happy new year.
