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.

Please answer the question below

The value of x in the given sector is determined as 7.1.

<h3>Area of the sector</h3>

Total area of the sector = area of the shaded + area of the unshaded

Since shaded and unshaded areas are equal, the value of x is calculated as follows;

πr²θ/360 = πx²60/360 +  πx²60/360

πr²θ/360 = 2(πx²θ/360)

πr² = 2(πx²)

r² = 2x²

x² = r²/2

x² = (10²)/2

x² = 50

x = √50

x = 7.1

Thus, the value of x in the given sector is determined as 7.1.
