Question

please help im sorry i dont understand shapes and angles

Answer 1

Answer:

Sorry I can't answer this.

But you may use the protacter to find the angle

Answer 2

? = 73°

There are 7 sides in this polygon

Calculate total interior angles using (n-2) * 180    

                                                                  ["n" denotes number of sides]

• Here total interior angle: (7-2)*180 = 900°

The missing angle inside the polygon:

900° - 130° -119° -130° -154° -130° -130°

900° - 793°

107°

A straight line has total 180°

? + 107° = 180°

? = 180° - 107°

? = 73°
