To get the missing angles of the right triangle, we first add the two acute angles (2x + 6) and (3x - 26) which is 5x - 20 = 180. Solving for x gives x = 40. Substituting this back into the expressions means the missing angles as 86 degrees and 94 degrees.

Therefore, the missing angles of the right triangle are 86 degrees and 94 degrees.
