The situation is shown in the picture attached.

You are given the two legs of the rectangular triangle, therefore, in order to find the angle, you need to apply the tangent definition:
tan(x) = Opposite leg / Adjacent leg

Now, invert the formula:
x = tan⁻¹(O / A)
= tan⁻¹ (880 / 1450)
= tan⁻¹ (0.60689)
= 31.25°

Hence, angle x is 31°.
