Answer:

1. 88 degrees.

2. x = 8.

3. x = 3.

4. y = 8.

Explanation:

1.

This is a hexagon where the sum of the internal angles = 720 degrees, so

x = 720 - (172 + 125 + 120 + 95 + 120)

= 720 - 632

= 88 degrees.

2.

If this is a parallelogram then opposite sides are equal , so:

2x = x + 8

x = 8

Checking the other 2 sides:

x = 3x - 16

-2x = -16

x = 8.

3.

This is a rhombus where all sides are equal, so:

x + 5 = 3x - 1

6 = 2x

x = 3.

5x - 7 = 2x + 2

3x = 9

x = 3.

4.

A rectangle where opposite sides are equal, so

2y + 4 = 3y - 4

8 = y

2y = y + 8

y = 8.
