Question

The three angles of the quadrilateral are  50° , 65° and 80°. Find the fourth angle.​

Answer 1

Answer:

165°

Step-by-step explanation:

Sum of all the angles of a Quadrilateral = 360°

Let the fourth angle be 'x'

Therefore, the fourth angle is;

x + 50° + 65° + 80° = 360°

x + 195° = 360°

x = 360° - 195°

x = 165°

Hope it helps.

Answer 2

Answer:

165°

Step-by-step explanation:

sum of all the angles of a quad. is 360°

360° = 80 + 65 + 50 + 4th angle

4th angle = 360 - 195

4th angle = 165°

The 4th angle is 165°
