Find the value of x in the figures.

Answer»

We know that ∠LOP + ∠PON + ∠NOM = 180°

[Linear pair: The two adjacent angles are said to form a linear pair of angles if their non–common arms are two opposite rays and sum of the angle is 180°]

Since, 35° + x° + 60° = 180°

x° = 180° – 35° – 60°

x° = 180° – 95°

xo = 85°
