Answer:
n = 32
Step-by-step explanation:
The sum of the interior angles of an n-sided convex polygon is ...
angleTotal = 180°·(n -2)
Your angleTotal is 5400°, so you have ...
5400° - 180°·(n -2)
30 = n -2 . . . . . . divide by 180°
32 = n . . . . . . . . .add 2
The value of n is 32.
Answer:
b) $640
Step-by-step explanation:
Competitor's price = $800
<u>Price, 20% below of competitor's:</u>
- $800 - 20% =
- $800*(100-20)/100 =
- $800*0.8 =
- $640
Correct answer choice is b) $640
Answer:
the telephone polé is 24ft.
Step-by-step explanation:
30^2-18^2=b^2
900-324=b^2
576=b^2
\sqrt[576]=sqrt(b^2]
24=b
b=hight of telephone
