How many sides does a regular polygon have that has an angle of 20
Answers
We divide the total sum of the angles by 20 =18 sides
Find the correct sum of these geometric series..*a1=343, an=-1, r= -1/7
*a1=80, n=7, r= -1/2
*a1= 3, a8=384, r=2
Please help me with these problems.. :(

That would be the transitivity of the equality.
An angle bisector of a triangle divides the opposite side of the triangle into segments 5 cm and 4 cm long. A second side of the triangle is 5.4 cm long. Find the longest and shortest possible lengths of the third side of the triangle.

the answer is 8.3 cm, 5.8 cm
Which is the solution set of the inequality 15y-9 < 36y>9/5
y<9/5
y < 3
y>3
Answers
In solving for the solution set of the inequality 15y - 9 < 36, much like any other algebraic equation, the first step should be to isolate y. This is done as follows:
15y - 9 < 36
Adding 9 to both sides of the equation: 15y - 9 + 9 < 36 + 9 15y < 45
Dividing both sides by 15 to isolate y: 15y/15 < 45/15 y < 3
Therefore the answer is the third choice y < 3.
Answer:
y<3
