Question

The three angles of a quadilateral are 76, 54, 108 Find the mesure of reflex of fourth angle and exterior of fourth angle,​

Answer 1

Answer:

Given that ;

Three Angles of the Quadrilateral ;

Frist Angle = 76°

Second Angle = 54°

Third Angle = 108°

Fourth Angle = ?

Let ,

The Fourth Angle be x

We Know That ;

Sum of 4 Angles of the Quadrilateral = 360°

76° + 54° + 108° + x = 360°

238° + x = 360°

x = 360° - 238°

x = 122°

Hence ;

Fourth Angle of the Quadrilateral ( x ) = 122°
