Answer:
is it asking for linear functions
0.9 ..............................
I believe that it would be a-21/49
Since the rectangles are similar. The ratio of their sides will be the same.
So, we can write:

Therefore, the left side of the bigger rectangle will be 12 units in length.
6 sin 2x = 6 cos x Using the identity sin 2x = 2 sin x cos x:-
12 sin x cos x = 6 cos x
6 cos x ( 2 sin x - 1) = 0
either 6 cos x = 0 or 2 sin x - 1 = 0 so sin x = 1/2
x = pi/2, 3pi/2 , pi/6, 5pi / 6
answer is ( pi/6, pi/2, 5pi/6, 2pi/2)
