Answer 2

Explanation:

4.i) angle1 + angle2 (pair 1)

angle4 + angle3 (pair 2)

angle5 + angle6 (pair 3)

angle7 + angle8 (pair 4)

ii) angle1 + angle3 (pair 1)

angle4 + angle2 (pair 2)

angle5 + angle8 (pair 3)

angle6 + angle7 (pair 4)

5.(3x+5)° + (2x-25)° = 180°. (linear pair)

3x+2x-20 = 180°

5x-20 = 180°

5x = 180+20 = 200°

x = 200/5

x = 40°

(3x+5)° = 3×40+5 = 120+5 = 125°

(2x-25)° = 2×40-25 = 80-25 = 55°

6.i) 90-42 = 48°

ii) 90-33.5 = 56.5°

7. i) 180-45.5 = 134.5°

ii) 180-150 = 30°
