#### Answer

$\angle$BOA and $\angle$COB $\angle$DOC and $\angle$EOD

#### Work Step by Step

The angles $\angle$BOA and $\angle$COB are complementary angles. $\angle$BOA + $\angle$COB = 25$^{\circ}$ + 65$^{\circ}$ = 90$^{\circ}$ The angles $\angle$DOC and $\angle$EOD are complementary angles. $\angle$DOC + $\angle$EOD = 15$^{\circ}$ + 75$^{\circ}$ = 90$^{\circ}$
