Given :
The diagonals of rhombus ABCD intersect at E.
∠CAD = 20°.
To Find :
The angle ∠CDA.
Solution :
We know, diagonals of a rhombus bisects each other perpendicularly.
So, ∠DEA = 90°.
In triangle ΔEAD :
∠EAD + ∠AED + ∠EDA = 180°
20° + 90° + ∠EDA = 180°
∠EDA = 70°
Now, we know diagonal of rhombus also bisect the angle between two sides .
So, ∠CDA = 2∠EDA
∠CDA = 2×70°
∠CDA =140°
Therefore, ∠CDA is 140°.

Answer:
without the numbers there is no answer
Step-by-step explanation:
A=P(1+(r/n))^nt
A: total
P: capital inicial
r: el interés anual
n: mensualmente/trimestralmente/etc.
t: después de _ años/meses/etc.
A=3300(1+(0.023/4))^4(5)
~ $37,009.63
