Answer:

1) ∠A = 90º   Square

2) ∠A = 140º Parallelogram

3) ∠A = 90º   Rectangle

4) ∠A = 95º  Rhombus

5) ∠A = 60º Trapezoid

6) ∠A = 41º Parallelogram

Step-by-step explanation:

There just some points I want to state:

Rhombus  is a quadrilateral with all sides being equal and opposite sides being parallel.  Also, the opposite angles are equal, and the the diagonals bisect each other at right angles (90º).

In order to find the angles, just consider:

Sum of internal angles = 360º

You may also note the complementary and supplementary angles.

Check the picture below

thus \bf s=\cfrac{r\theta\pi }{180}\qquad 
\begin{cases}
s=\textit{arc's length}\\
r=radius\\
\theta=\textit{angle in degrees}\\
----------\\
r=3\\
\theta=10
\end{cases}\implies s=\cfrac{3\cdot 10\cdot \pi }{180}
