This resource combines geometry practice with a fun Halloween pumpkin reveal activity.

I can now see the picture portion of the worksheet. It shows two images: an already-colored pumpkin at the top and a black-and-white outline of the same pumpkin below. The black-and-white version has various sections numbered from 1 to 48, corresponding to the problems on the right side of the worksheet.

The task is to:
1. Calculate the missing angle 'x' for each triangle problem (numbered 1-48) using the fact that the sum of angles in a triangle is 180°.
2. Use the color key to determine which color to use for each numbered section based on the calculated value of 'x'.
3. Color the corresponding numbered sections in the black-and-white pumpkin image.

Let me solve a few more problems to demonstrate the pattern:

4. Problem 4: x = 60°, 50°
- x = 180° - 60° - 50° = 70°
- This falls in the "Green" category (x = 70°)

5. Problem 5: x = 40°, 60°
- x = 180° - 40° - 60° = 80°
- This falls in the "Blue" category (80° ≤ x < 90°)

6. Problem 6: x = 80°, 30°
- x = 180° - 80° - 30° = 70°
- This falls in the "Green" category (x = 70°)

The solution process involves systematically working through all 48 problems, calculating the missing angle for each, and then coloring the corresponding section in the pumpkin image according to the color key.

Since there are 48 problems, I'll summarize the approach rather than solving all of them individually:
- For each problem, subtract the two given angles from 180° to find the missing angle 'x'.
- Match the calculated value of 'x' with the appropriate color category from the key.
- Color the corresponding numbered section in the pumpkin image.

The final result will be a colored pumpkin image where each section is colored according to the calculated angle values, creating a Halloween-themed picture through this mathematical activity.

This worksheet combines geometry (finding missing angles in triangles) with a fun coloring activity, making it an engaging educational tool.
