What is the value of x in the equation?
x- 4/9 = 2/11

f. x= -62/99

g. x= -26/99

h. x= 26/99

i. x= 62/99

if there is work add : )

X-4/9 = 2/11
x-44/99=18/99
x=62/99
So answer I

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
