Identify the angle that is opposite the hypotenuse.

A right triangle $ABC$ABC is depicted with the right angle located at vertex $C$C. The triangle is oriented such that vertex $A$A is at the top, vertex $B$B is at the bottom left, and vertex $C$C is at the bottom right. $\angle BAC$BAC has a measurement of θ degrees, and $\angle ABC$ABC has a measurement of ɑ degrees. Side $AB$AB is opposite of the right angle $ACB$ACB. Side $BC$BC is opposite of $\angle BAC$BAC. Side AC is opposite of $\angle ABC$ABC.
