ANSWER

Answer 2

$\large\mathfrak \pink{Solution:-}$

1) x + 2x + 3x = 180° (Angle sum property of a triangle.)

or, x + 2x + 3x = 180°

or, 6x = 180°

or, x = $\cancel\frac{180°}{6}$

or, x = 30°

2) PQ = PR

So, ∠PQR = ∠PRQ (Angles opposite to equal sides are equal.)

So, x + 50° + 50° = 180°

or, x + 100° = 180°

or, x = 180° - 100°

or, x = 80°

3)x + 2x + 90° = 180°(Angle sum property of a triangle.)

x + 2x + 90° = 180°

or, 3x + 90° = 180°

or, 3x = 180° -90°

or, 3x = 90°

or, x = $\cancel\frac{90°}{3}$

or, x = 30°

4)122° + 30° + x = 180°(Angle sum property of a triangle.)

122° + 30° + x = 180°

or, 152° + x = 180°

or, x = 180° - 152°

or, x = 28°
