There is a way to solve for the interior angles of the polygon add up to, by using the expression: (Note: n being the side: (n - 2)180
solve for the 14 angles first. Plug in 14 for n
14 - 2 = 12
12 x 180 = 2160
All of the angles combined together = 2160°. Note that it is given to us that 13 of the angles = 2016°
Solve for the last angle. Set the last (14th) angle as x:
x + 2016 = 2160.
Isolate the x. Note the equal sign, what you do to one side, you do to the other. Subtract 2016 from both sides
x + 2016 (-2016) = 2160 (-2016)
x = 2160 - 2016
x = 144
Answer: The 14th angle must be 144°

Answer:
y = -1
Step-by-step explanation:
(y+1)/(x-8) = (-1+1)/(-2-8)
(y+1)/(x-8) = 0
y+1 =0
y= -1
17.5cm squared
Explain: rectangle 7x5= 35
as this triangle is half of a 7x5 rectangle
35 divided by 2 = 17.5
Answer:
$11543.63
Step-by-step explanation:
<u>Plug information into A=P(1+r/n)^nt</u>
13000 = P(1+(.04/2))^(2*3)
13000 = P(1.02)^6
<u>Isolate P</u>
13000/(1.02^6) = P
P = $11543.63
Answer:
1/8 mile
Step-by-step explanation:
This is a subtraction problem. We need to subtract 5/8 from 3/4. We need a common denominator of 8.
3/4 - 5/8 = 6/8 - 5/8 = 1/8
Answer: 1/8
