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°`
