Factors of 76: 1 2 4 19 38 76
Factors of 160: <span>1 2 4 5 8 10 16 20 32 40 80 160
Any number that you see in both lists is a factor of both of them.</span>
EF(g) corresponds HJ(i)
FG(e) corresponds JI(h)
GE(f) corresponds IH(j)
(h/e)*f=(23.4/11.7)*13.05=26.1
Answer C: 26.1
if two opposite sides are 4cm each then their total length is 8cm. If the total length is 24cm then to work out the possible lengths of the other two sides you subtract 8 from 24 which gives you 16. A rule in rectangles is that opposite sides are equal so each remaining side would have a length of 16/2 which is 8. To get all the possible answers you have to go through all the possible perimeters (assuming all perimeters have to be whole numbers) between 24(max) and 9(min) and do those steps.
Answer:
I assume that there are parentheses missing from the question and that it should be
Prove that 1 + sin 2A + cos 2A ---------------------------------------------- = cot A
1+sin2A−cos 2A
Use sin 2 A= 2 sin A cos A and
cos 2 A = 1−2 sin 2 A and cos 2 A = 2 cos A−1
