Question 3
Find x
1)
We know that,
Sum of all angles of a triangle is 180°
Therefore,
∠A + ∠B + ∠C = 180°
x + 50° + 60° = 180°
x + 110° = 180°
x = 180° - 110°
x = 70°
___________________________
2)
We know that,
Sum of all angles of a triangle is 180°
Therefore,
∠R + ∠P + ∠Q = 180°
x + 90° + 30° = 180°
x + 120° = 180°
x = 180° - 120°
x = 60°

3)
We know that,
Sum of all angles of a triangle is 180°
Therefore,
∠Z + ∠Y + ∠X = 180°
x + 110° + 30° = 180°
x + 140° = 180°
x = 180° - 140°
x = 40°
___________________________
4)
We know that,
Sum of all angles of a triangle is 180°
Therefore,
x + x + 50° = 180°
2x = 180° - 50°
x = 130°
x = 130° / 2
x = 65°
one x = 65° another x = 65°
___________________________
5)
We know that,
Sum of all angles of a triangle is 180°
Therefore,
x + x + x = 180°
3x = 180°
x = 180° / 3
x = 60°
1st x = 60° , 2nd x = 60° , 3rd x = 60°
___________________________
6)
We know that,
Sum of all angles of a triangle is 180°
Therefore,
x + 2x + 90° = 180°
3x + 90° = 180°
3x = 180° - 90°
3x = 90°
x = 90° / 3
x = 30°
2x = 3x - x
2x = 90° - 30°
2x = 60°
