The complete question in the attached figure
we know that
the diagonals of a rhombus intersect to form right angles,
so
angle ACE is ----------> (90°-64°)-----------> 26°
ACE is the angle bisector of ACD, this means that ACD is ---------> 26 x 2 = 52°
The diagonals are angle bisectors to the opposite corners
so
ACD = ACB = 52°
and
BCD = 52 x 2 = 104°
For a rhombus, opposite angles are equivalent,
so
BAD = BCD = 104°
the answer is
angle BAD=104°
Do you want a proof or just the answer?
The answer is: the square (2.5x2.5).

Answer:
<h2>x = 28</h2>
Step-by-step explanation:
ΔARP and ΔCRD are similar. Therefore the sides are in proportion:
![\dfrac{AR}{CR}=\dfrac{PR}{DR}](https://tex.z-dn.net/?f=%5Cdfrac%7BAR%7D%7BCR%7D%3D%5Cdfrac%7BPR%7D%7BDR%7D)
We have:
AR = 10 + x
CR = x
PR = 15 + 42 = 57
DR = 42
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>
![(42)(10)+(42)(x)=57x](https://tex.z-dn.net/?f=%2842%29%2810%29%2B%2842%29%28x%29%3D57x)
<em>subtract 42x from both sides</em>
<em>divide both sides by 15</em>
