Answer: 53.6

Explanation:

When given a side and its opposing angle and another angle, to find its opposing side you may use the sine rule.

sin(Angle)/opposing side = sin(Angle)/opposing side

Applying this formula will give us the following:

1) sin90/x = sin66/49
2) 1/x = 0.01864
3) 1/0.01864 = x
4) x ≈ 53.6

Hope this helps, brainliest would be appreciated :)
