Answer:
11
Step-by-step explanation:
or 
At the point/angle E:
- the adjacent side(side <u>next to</u> the point/angle) is ED
- the opposite side(side of the triangle <u>across</u> from the point/angle) is DF
- the hypotenuse (the<u> longest side</u> of the triangle) is EF.
sin ∠E = 
sin ∠E =

2x-7y=18 _(1)
-2x+4y=5
11y=23 , Y=23/11 sub in 1
2x-7×23/11=18
2x = 18×11 + 7×23
x = ( 198 + 161 )/2 = 359/2
Answer:
A) 1/6
Step-by-step explanation:
Common Ration means you need to divide second term/first term, third term/2nd term
12/72 = 1/6
2/6 = 1/6
Therefore the common ratio is 1/6
