Answer:
n = 20.
Step-by-step explanation:
The external angles of a polygon add up to 360 degrees. So:
30 + 42 + 16(n - 2) = 360 where n is the number of sides of the polygon.
16n + 30 + 42 - 32 = 360
16n + 40 = 360
16n = 320
n = 20.
ANSWER

EXPLANATION
The given problem is

This is defined if and only if

Even the given expression can be simplified to obtain:

The exclusion is

Answer:
(2, 14), (3, 7)
Step-by-step explanation:
The way these angles are numbered, corresponding angle numbers differ by 4, 8, or 12.
Corresponding angles are ...
Angle 2 and Angle 14 . . . . . . numbers differ by 12
Angle 3 and Angle 7 . . . . . . . numbers differ by 4
_____
If a given angle is Northwest of the intersection, any corresponding angle will also be Northwest of its intersection. Corresponding angles are ...
northwest: {1, 5, 9, 13}
northeast: {2, 6, 10, 14}
southeast: {3, 7, 11, 15}
southwest: {4, 8, 12, 16}
Any pair of numbers from the same set will be corresponding angles.
Answer:
c 11.25 I think is correct
Step-by-step explanation:
B.
if he is just talking about the length than it is,
4(13x + 8)
of he is talking about overall length he swam than,
4(13x + 8) + 3(7x - 2)
c.
if x = 12
than
perimeter = 2l + 2b
so, after inserting the values we got,
→ 2[13(12) + 8] + 2[7(12) - 2]
→ 2 (156 + 8) + 2(84 - 2)
→ 2 × 164 + 2 × 82
→ 328 + 164
→ 492 ft. ← perimeter
and yeah, according to me
a is wrong as,
formula of perimeter = 2l + 2b or 2(l+b)
so, the answer should be,
2(13x + 8) + 2(7x - 2) or 2 [ (13x + 8) + (7x - 2)
