Question

Find the angle measure x in the following figures. (a)​

Answer 1

Answer:

$In \: a \: quadrilateral \: sum \: of \: all \: angles \: is \: equal \: to \: 360 \\ = 50 + 130 + 120 + x = 360 \\ = x + 300 = 360 \\ = x = 360 - 300 \\ = x = 60 \: \\hope \: it \: helps \: u \::)$

Answer 2

Sum of the angles in a quadrilateral = 360°.

》 50° + 130° + 120° + x = 360°

》 300° + x = 360°

》 x = 360° - 300°

》 x = 60°.

Therefore, x = 60°.
