Answer 2

Answer: In this figure, we can apply both linear pair and angle sum property of pentagons.

90° + (180-90)° + (180-70)° +(180-60)° + x° = 540° {Both linear pair and angle sum property of pentagons}

i.e, 90° + 90° + 110° + 120° + x = 540°(Sum of all sides of a pentagon)

Therefore, 410° + x° = 540°

i.e, x = 540° - 410° = 130°
