Option C:
interior angle 144°, exterior angle 36°
Solution:
The given image is a regular decagon.
Therefore the number of sides (n) = 10
Each interior angle =
Each interior angle = 144°
Each exterior angle =
Each exterior angle = 36°
Hence interior angle 144°, exterior angle 36°.
Option C is the correct answer.
Area is the space inside a shape
Answer:
a) + 6x + 8
b) 6 - 7x
c) - 7x +4
d) 2x + 5
Step-by-step explanation:
a) (5x + 4) – (x – 2)
(5x + 4) (-x + 2)
+ 10x - 4x + 8
+ 6x + 8
b) (6 – 3x) + (x – 5x)
6 – 3x + x – 5x
6 - 7x
c) (4x + 5) – (3x – 2) – 6
(4x + 5) (–3x + 2) – 6
+ 8x -15x + 10 -6
- 7x +4
d) 9x + 5 – 7x
2x + 5
