Let's solve each of the problems step by step using the angle rules provided:

---

1)

We have a right angle (90°) split into two parts: one is 70°, and the other is missing.

- A right angle = 90°
- One part = 70°
- So, missing angle = 90° − 70° = 20°

✔ Answer: 20°

---

2)

A straight line with one angle given as 40°. The total on a straight line is 180°.

- Straight line = 180°
- Given angle = 40°
- Missing angle = 180° − 40° = 140°

✔ Answer: 140°

3)

Right triangle with one angle = 40°, and a right angle (90°). We need the third angle.

- Sum of angles in a triangle = 180°
- Known angles: 90° + 40° = 130°
- Missing angle = 180° − 130° = 50°

✔ Answer: 50°

4)

Triangle with two angles: 35° and 35°.

- Sum of angles in a triangle = 180°
- Total known = 35° + 35° = 70°
- Missing angle = 180° − 70° = 110°

✔ Answer: 110°

5)

Angles around a point: total = 360°

Given:
- 55°
- 200°
- One missing angle

So:
- Sum of known angles = 55° + 200° = 255°
- Missing angle = 360° − 255° = 105°

✔ Answer: 105°

---

6)

We have a straight line with three angles: 33°, 68°, and one missing angle.

- Straight line = 180°
- Sum of known angles = 33° + 68° = 101°
- Missing angle = 180° − 101° = 79°

✔ Answer: 79°

---

✔ Final Answers:

1) 20°
2) 140°
3) 50°
4) 110°
5) 105°
6) 79°
