Answer:
Each angle is equal to 108 degrees. The internal angles of a pentagon add up to 540.
No matter what the side lengths are, so long as it is a regular pentagon, each angle will always be exactly 108 degrees.
20.2m-11.8
Incase your wondering what happened to the y it got canceled out because they were equal on both sides.
I am pretty sure it would form a acute angle!
Step-by-step explanation:
The surface area of a square pyramid is the area of the square base plus the area of the 4 lateral faces:
A = b² + 4 (½ bl)
A = b² + 2 bl
where b is the width of the base,
and l is the slant height.
Hello there!
-3| 2x + 6| = -12
2x + 6 = -12/-3
2x + 6 = 4
Solve absolute value
We know that 2x + 6 = 4 or 2x + 6 = -4
We have two possibilities to solve this.
1)
2x + 6 = 4
2x = 4 - 6
2x = -2
Divide both sides by -2
2x/-2 = -2/-2
x = 1
2) 2x + 6 = -4
2x = -4 - 6
2x = -10
Divide both sides by 2
2x/2 = -10/2
x = -5
Answer : X = -1 or X = -5
A+ Guaranteed!
