## Extra Questions Part 2

Question 6: Find the angle x

Answer: We know that, angle sum of a triangle = 180⁰
So, 35° + x + x = 180°
Or, 35° + 2x = 180°
Or, 2x = 180° - 35° = 145°
Or, x = 145°÷2 = 72.5°

Question 7: Find the angle x

Answer: We know that, angle sum of a triangle = 180⁰
So, 30° + x + x = 180°
Or, 30° + 2x = 180°
Or, 2x = 180° - 30 ° = 150°
Or, x = 150°÷2 = 75°

Question 8: Find the angle y

Answer: We know that, angle sum of a triangle = 180⁰
So, 27° + x + x = 180°
Or, 27° + 2x = 180°
Or, 2x = 180° - 27° = 153°
Or, x = 153°÷2 = 76.5°

Question 9: Find the angle y

Answer: We know that, angle sum of a triangle = 180⁰
So, 90° + y + y = 180°
Or, 90° + 2y = 180°
Or, 2y = 180° = 90°
Or, y = 90°÷2 = 45°

Question 10: Find the angle y

Answer: We know that, angle sum of a triangle = 180⁰
So, y + y + y = 180°
Or, 3y = 180°
Or, y = 180°÷3 = 60°
