Solution:

We know that:

$\angle A = 38\°$
$\angle B = 90\°$
$\angle A + \angle B + \angle C = 180$
$\angle C + n = 180$

Step by step calculations:

1. Substitute the angles in the equation "∠A + ∠B + ∠C = 180" to find ∠C:

$\angle A + \angle B + \angle C = 180$
=> $38 + 90 + \angle C = 180$
=> $128 + \angle C = 180$
=> $\angle C = 180 - 128$
=> $\bold{\angle C = 52}$

2. Substitute ∠C in the equation "∠C + n = 180" to find n:

$\angle C + n = 180$
=> $52 + n = 180$
=> $n = 180 - 52$
=> $\bold{n = 128}$
