Answer 2

Solutions :-

We have,

Three angles of a quadrilateral➠

First angle = 70°

Second angle = 95°

Third angle = 80°

Fourth angle = ?

Let the fourth angle be x

We know that the sum of all angles of a quadrilateral is 360°

A/q

=> 70° + 95° + 80° + x = 360°

=> 245° + x = 360°

=> x = 360° - 245° = 115°

Hence,

Fourth angle is 115°   ✔
