please mark as brainliest

Answer 2

Given:

$\[\angle A = 50^\circ \]$

Solution:

Refer to he figure given below,

Angle A and angle D are the adjacent angle on non-parallel side,

$\[\begin{array}{l}\therefore \angle D = 180^\circ - \angle A\\ \Rightarrow \angle D = 180^\circ - 50^\circ \\ \Rightarrow \angle D = 130^\circ \end{array}\]$

Hence the measure of angle D is $\[130^\circ \]$.
