Answer:
A, B, C, & E
Step-by-step explanation:
A) 19,456 ÷ 6 = 3,242
(2/3 is 0.666666666 etc)
B) 28,765 ÷ 13 = 2,212.692308...
C) 4,145 ÷ 3 = 1,381
(2/3 is 0.666666666 etc)
D) 4,165 ÷ 17 = 245
(Not bolded because it is not an answer)
E) 44,312 ÷ 16 = 2,769.5
C -> When dividing by three, if the first number's values do not add up to a multiple of 3 there will be a remainder. Example from your problem,
4,145 -> 4 + 1 + 4 + 5 = 14 -> 14 is not a multiple of 3, so there is a reminder
D -> No decimal / fraction, no remainder!
Have a nice day!

Answer:
4) 95.7 m
Step-by-step explanation:
The angle at the cliff base between Alan and Keith is ...
B = 180° -29° -48° = 103°
The law of sines will tell you the distance KB from Keith to the cliff base is
KB/sin(A) = KA/sin(B)
KB = KA×sin(A)/sin(B) = (70 m)sin(29°)/sin(103°) ≈ 34.82935 m
The height of the cliff is found from the tangent relation ...
Tan = Opposite/Adjacent
tan(70°) = height/(34.83 m)
height = (34.83 m)tan(70°) = 95.693 m
The height of the cliff is about 95.7 m.

<em>Additional comment</em>
These problems can usually be resolved into two 2-D problems. Here, we can work out the distance we need from Keith to the cliff by considering only the ground plan of the site. Then we can work out the height of the cliff only considering the vertical plane containing Keith and the base of the cliff.
The attachment shows the ground plan triangle KAB.
