Question

three angles of a quadrilateral ate 76°, 114°and86°. The fourth angle of the quadrilateral is​

Answer 1

Answer:

84

Step-by-step explanation:

By Angle sum property of quadrilateral

sum of all angles = 360

76+114+86+4th angle = 360

276 + 4th angle = 360

4th angle = 360-276

4th angle = 84

Answer 2

The 4th angle is 84°

Angles in a quadrilateral sum up to 360°

< 1 = 76° , < 2 = 114° , < 3 = 76°

let the 4th angle be x.

76 + 114 + 86 + x  = 360°

276 + x = 360°

x = 360 - 276

x = 84°
