## Extra Questions

### Part 1

Question 1: Find the angle x

Answer: We know that, angle sum of a triangle = 180⁰
So, 60° + 35° + x = 180°
Or, 95° + x = 180°
Or, x = 180° - 95° = 85°

Question 2: Find the angle x

Answer: We know that, angle sum of a triangle = 180⁰
So, 65° + 45°+ x = 180°
Or, 110°+ x = 180°
Or, x = 180° - 110° - 70°

Question 3: Find the angle x

Answer: We know that, angle sum of a triangle = 180⁰
So, 62°+ 74° + x = 180°
Or, 136° + x = 180°
Or, x = 180° - 136° = 44°

Question 4: Find the angle x

Answer: We know that, angle sum of a triangle = 180⁰
So, 62° + 72°+ x = 180°
Or, 139°+ x = 180°
Or, x = 180°- 139°= 41°

Question 5: Find the angle x

Answer:We know that, angle sum of a triangle = 180⁰
So, 84°+ 55°x = 180°
Or, 139° + x = 180°
Or, x = 180°- 139°= 41°
