The measure of 5 of the interior angles of a hexagon are 110, 120, 90, 140, and 125. what is the measure of the smallest exterio
Romashka-Z-Leto [24]

Answer:

A) 40

Step-by-step explanation:

The sum of the interior angles of a regular polygon is:

(n - 2) \times 180

For a hexagon, we put n=6

(6 - 2) \times 180 = 4 \times 180 = 720

Let x be the 6th interior angle, then

x + 110  + 120 + 90 + 140 + 125 = 720

x + 585 = 720

x = 720 - 585 = 135

The largest interior angle is 140°

Therefore the least exterior angle will be:

180 - 140 = 40

The correct choice is A

Help now plz it’s due in 8 minutes
Reptile [31]

Answer:

<em>9%</em>

Step-by-step explanation:

Original rectangle: 100 cm by 200 cm

Original area: 100 cm * 200 cm = 20,000 cm^2

Reduced by 70%, the measures are now 30% of they they were.

30% of 100 cm = 30 cm

30% of 200 cm = 60 cm

New area: 30 cm * 60 cm = 1800 cm^3

New area equals what percent of original area?

1800/20,000 * 100 = 9%
