The bottom of a ladder rests on the ground and the top of the ladder rests against a wall. The ladder forms a 66° angle with the ground and the top of the ladder is positioned 11 meters up the wall. Which is the exact measure of the ladder in meters? a) 11/sin(66°) meters
b) sin(66°)/11 meters
c) sin(66°/11) meters
d) sin(11°/66) meters​

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

college

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

what level of math? also i don't need to be paid if i can you.
