If two adjacent angles are complementary angles, the included angle of bisectors of these two angles is (45 degrees).

If two adjacent angles are complementary angles, the included angle of bisectors of these two angles is (90 degrees).

Let the first angle be X 1 and the second angle be X2.

Then 2/3X 1+X2=90.

X2+5/3X 1= 180

X 1=90 degrees

X2=30 degrees
