Answer:
The angle of the unknown measure is <em>27°.</em>
Step-by-step explanation:
When we look at this angle, we can see it is a <em>90° angle</em>. Since we already have <em>63°</em> of the angle, we just <em>subtract 90° from 63°</em> and we get <em>27°. </em>Therefore, <em>27° is our answer.</em>
