Answer:
Step-by-step explanation:
The sum of the measures of the interior angles of each convex n-sided polygon is always equal to
1. A pentagon is 5-sided polygon, then the sum of the measures of the interior angles of pentagon is
2. An octagon is 8-sided polygon, then the sum of the measures of the interior angles of octagon is
3. A dodecagon is 12-sided polygon, then the sum of the measures of the interior angles of dodecagon is
4. For 40-sided polygon the sum of the measures of the interior angles is
5. For 52-sided polygon the sum of the measures of the interior angles is
6. For 100-sided polygon the sum of the measures of the interior angles is
Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0
2*(y^2 - 5y - 84) = 0 This factors into
2*( y - 12) (y + 7) = 0
y = 12
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
It's 7,000 because 1,000*7 = 7000
