Answer:
Angles 2, 3, 6, 7
Step-by-step explanation:
Since supplementary means to add up to 180 degrees, or a straight angle, we just find which angles are connected with a straight line.
These angles would be Angle 2 and Angle 3.
Since we have a whole figure, we also need to find the corresponding angles for Angle 2 and Angle 3. (Corresponding angles are the same degree as the original angle.)
The Corresponding angles to Angle 2 and Angle 3 are Angle 6 and Angle 7 respectively.
Thus, our answer is Angles 2, 3, 6, and 7.

Step-by-step explanation:
Answer:
Perimeter: 33.7 mm
Area: 54 mm
Step-by-step explanation:
If you do 12 + 9.7 + 12 you will get the perimeter, and to get the area you would use the formula A = 
x base x height. Since the base is 12 and the height is 9, you would do 12 x 9 x 0.5 to get 54 mm for the area of the triangle.
