$$\mathrm{\angle }ADC+\mathrm{\angle }ABC=180°$$$$\Rightarrow \mathrm{\angle }ADC=180°-158°=22°$$$$\mathrm{\angle }ADE+\mathrm{\angle }ADC=90°$$$$\Rightarrow \mathrm{\angle }ADE=90°-22°=68°$$$$\mathrm{\angle }ABE=\mathrm{\angle }ADE=68°$$

$$or$$$$\mathrm{\angle }EBC=90°$$$$\Rightarrow \mathrm{\angle }ABE=158°-90°=68°$$$$\mathrm{\angle }ADE=\mathrm{\angle }ABE=68°$$
