-find the measurements of the triangle (8&6) and the rectangle (8&10)
-find the areas of the triangle (l x h divided by 2= a) and the rectangle (l x h+a)
-add the areas together (24& 80)
51) The answer is 800ft
Steps:
-split the irregular shape into a triangle and a rectangle
-find the area of both the triangle (200) and of the rectangle (600)

Answer:

x = 38

y = 25

Step-by-step explanation:

To find x, you do

(2x + 5) = (3x - 33)

Subtract 2x from both sides to isolate x on one side, you get:

5 = (x - 33)

Add 33 to both sides to separate the normal number from the x, you get:

38 = x

From there, you plug x into one of the equations

2(38) + 5

The answer's 81, meaning that angle is 81 degrees. Using supplementary angles, you can find that angle ACD = 99, which you can use to find angle BCE. You'll get this equation:

(4y - 1) = 99

Add one to both sides to get rid of it, you get:

4y = 100

Divide by four, to get the y all alone:

y = 25

I hope this helped!

Maximum packets that can be obtained is 9 packets because only 9 packets with 5 green beads each can be packaged.
