Question

if three angles of a quadrilateral is 90 degree, 50 degree and 45 degree then find the fourth angle​

Answer 1

Step-by-step explanation:

We know that angle sum of a quadrilateral is 360°

Let the fourth angle be x

90° + 50° + 45° + x = 360°

⇒ 185° + x = 360°

⇒ x = 360°-185°

⇒ x = 175°

The fourth angle is 175°
