Answer:
60° = <em>m</em>∠<em>CED</em>
30° = <em>m</em>∠<em>AEB</em>
Step-by-step explanation:
Since 90° is the <em>m</em>∠<em>CEB</em><em>,</em><em> </em>we already know the angle measures of the other two that got to be half and half of each other:
m∠<em>AEB</em> = ½<em>m</em><em>∠</em><em>CED</em>

This is like the 30°-60°-90° theorem. Always keep these in mind because you will never know when they will come in handy. The other one is called the 45°-45°-90° theorem, which in this case would not apply because two legs would have to congruent, which in this case they are not.
