<em>Answer:</em>

<em>63°</em>

<em>Step-by-step explanation:</em>

<em>Hi there ! </em>

<em>ABCD parallelogram => ∡A = ∡C</em>

<em>13x - 41 = 6x + 15</em>

<em>13x - 6x = 15 + 41</em>

<em>7x = 56</em>

<em>x = 56 : 7</em>

<em>x = 8</em>

<em>∡C = 6×8 + 15 = 48 + 15 = 63°</em>

<em>Good luck !</em>
