<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>
Look it up find the answer on google
V = 2ab + 2ca + 2bc
2ab + 2ca = V - 2bc
2a * b + c = V - 2bc
Answer: a = v - 2bc / 2 * b + c
Hope that helps!!!!! : )
