Answer:
45°
Step-by-step explanation:
[tex] \angle \: 1 \cong \angle \: 2...(given)..(1) \\ \angle \: 1 + \angle \: 2 = 90 \degree....(given)..(2) \\ from \: (1) \: and \: (2) \\ \angle \: 1 + \angle \: 1 = 90 \degree \\ \therefore \: 2\angle \: 1 = 90 \degree \\ \therefore \: \angle \: 1 = \frac{90 \degree}{2} \\ \therefore \: \angle \: 1 = 45 \degree \\ \implies \: \angle \: 2 = 45 \degree \\ \\ \: \: \: \: \: \: \orange{ \boxed{ \therefore \: \angle \: 1 = \angle \: 2= 45 \degree }}[/tex]
