Answer 2

Step-by-step explanation:

Let the measures of equal angles of quadrilateral be x degree

Since, sum of all the angles of a quadrilateral is 360°

Therefore,

50° + 50° + x + x = 360°

$\therefore \: 100 \degree \: + 2x = 360 \degree \\ \implies \: 2x = 360 \degree - 100 \degree \\ \implies \: 2x = 260 \degree \\ \implies \: x =\ \frac{ 260 \degree }{2} \ \\ \implies \: x = 130 \degree$

Thus the measure of the each of two angles is 130°.
