Yes, you can.

The measure of the interior angle next to the given exterior angle is:

Interior angle = 180 - Exterior angle = 180 - 160 = 20 degrees

Then, you know two of the interior angles of the triangle, and you know that all three angles must sum to 180:

Missing interior angle + Known interior angle + 90 = 180

Missing interior angle = 180 - 90 - Known interior angle

Missing interior angle = 180 - 90 - 20 = 70 degrees

Since it is a right triangle one angle is 90%5Eo
The angle with exterior measure of 160%5Eo has interior angle 180%5Eo-160%5Eo+=+20%5Eo (sum of supplementary angles is 180%5Eo)
Finally, the 3rd angle must be 180%5Eo+-+90%5Eo+-+20%5Eo+=+70%5Eo (sum of angles of triangle is 180%5Eo)
