Answer:​

Answer 1

Answer:

fourth angle is 122 °

Step-by-step explanation:

by using angle sum property of quadrilateral.

x+76+54+108=360

x+238=360

x=360-238

x=122°

Answer 2

Answer:

122°

Step-by-step explanation:

In quadrilateral the sum of four angles is always 360°

So, 76°+54°+108°+x°=360°

238°+x°=360°

x°=360°-238°

x°=122°

So, the fourth angle of quadrilateral will be 122°
