Step-by-step explanation:
1. The sum of all angles in a triangle is 180°
75° + 60° + x° = 180°
135° + x° = 180°
x° = 55°
2. The sum of all angles in a triangle is 180°
70° + 70° + x° = 180°
140° + x° = 180°
x = 40°
3. The sum of all angles in a triangle is 180°
1 : 2: 5 = 1x:2x:5x
1x + 2x + 5x = 180°
8x = 180°
x = 22.5°
2x = 45°
5x = 112.5°
4. The sum of all angles in a triangle is 180°. The angle in a line is 180°
Missing angle is 180° - 123° = 57°
The sum of angles in a triangle is 180°
57* + x° + 90* = 180°
57° + x° = 90°
x = 33°
5. We know that the sum of angles in a triangle is 180°. We can subtract the values of the two other angles from 180* to find the missing angle.
