1. 75°

2. 55°

3. 50°

4. 75°

5. 55°

6. 130°

7. 50°

8. 130°

9. 50°

10. 105°

11. 75°

12. 105°

Step-by-step explanation:

1. Vertically opposite angles are equal (based on 4.)

2. Vertically opposite angles are equal (based on 5.)

3. Vertically opposite angles are equal.

4. Alternate angles are equal.

5. Sum of angles in a triangle is 180° (based on 7.)

6. Corresponding angles add up to 180°

7. Alternate angles are equal.

8. Vertically opposite angles are equal (based on 6.)

9. Vertically opposite angles are equal. (based on 7.)

10. Corresponding angles add up to 180° (based on 4.)

11. Vertically opposite angles are equal.

12. Vertically opposite angles are equal (based on 10.)

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

yes because they have the same amount of green and blur marbles.
