Question

if for a quadrilateral ABCD, m angle A=50°, m angle B=130°, m angle D =120° then find the m angle C​

Answer 1

Answer:

M angle A + M angle C = 180°

= 130° + 50° = 180°

To find , M angle C

M angle D + M angle C = 180°

Here , we denote M angle C as x

= 120° + x = 180°

x = 180° - 120°

x = 60°

So , M angle C = 60°

Answer 2

M angle A + M angle C = 180°

= 130° + 50° = 180°

To find , M angle C

M angle D + M angle C = 180°

Here , we denote M angle C as x

= 120° + x = 180°

x = 180° - 120°

x = 60°

So , M angle C = 60°
