a) Sum of all the interior angles of a Pentagon is 540°.
So,
x + 40° + x + (180°-110°) +(180°- 50°) = 540°
→ 2x + 40° -160° = 540° - 180° - 180°
→ 2x = 180° + 160° - 40°
→ x = 150°
b) Sum of all the interior angles of quadrilateral is 360°.
So,
x + 60° + (180° - 110°) + 90° = 360°
→ x = 140°
Thankyou!!!
So,
x + 40° + x + (180°-110°) +(180°- 50°) = 540°
→ 2x + 40° -160° = 540° - 180° - 180°
→ 2x = 180° + 160° - 40°
→ x = 150°
b) Sum of all the interior angles of quadrilateral is 360°.
So,
x + 60° + (180° - 110°) + 90° = 360°
→ x = 140°
