Answer:
The first one is correct.
Hope this helps
Mark me brainliest if I'm right :)
First you need to find the sum of all the interior angles using the formula (n-2)*180, where n is the number of sides.
There are 6 sides to this figure so the interior angles need to equal (6-2)*180 = 4*180 = 720.
Now add all the given angles together: 2x + 3x + 3x + 3x +3x +2x = 16x
Now we know 16X = 720
Find X by dividing both sides by 16:
X = 720 / 16
X = 45
Now we know X, so to find E, replace X with 45 and multiply by 3:
3X = 3(45) = 135.
E = 135. The answer is D.

Step-by-step explanation:

Let the total seed packets needed Anthony to have 90 plants be x.
then,
64:32 :: 90:x
2:1 :: 90:x
90 = 2x
x = 45 seed packets.
________________________
64 plants = 32 seed packets.
1 plant =

seed packets.
90 plants =

seed packets.
Anthony need 45 seed packets to have 90 plants.
