Answer:

(a) 6.2 cm

Explanation:

You don't need to know much about trig here. You only need to know that the other acute angle in the triangle is less than 55°, so the measure of side x will be less than 8.9. Only one answer choice qualifies:

x ≈ 6.2

__

If you actually want to do the trig, as opposed to simply rejecting unreasonable choices, then you want to make use of the tangent relation.

Tan = Opposite/Adjacent

tan(55°) = 8.9/x

x = (8.9 cm)/tan(55°) ≈ 6.23 cm

x ≈ 6.2 cm
