Answer:
Step-by-step explanation:
(3x -2) - (4x +1)
= 3x - 2 - 4x - 1
= - x - 3
The number of angles equal the number of sides
The number of angles calculate: (n-2)x180°
(n-2)x180°=2700° |divide both sides by 180°
n-2=15 |add 2 to both siedes
n=13
Answer: 13 sides.
Answer:
56
Step-by-step explanation:
Since ABCD is a parallelogram, AB= DC

Simplifying the equation

Divide 3 on both sides, to get
