Answer 1

Answer:

The fourth angle of the quadrilateral is 122°

Step-by-step explanation:

When we solve 360 - (76 + 54 + 108),

We get 122 as the fourth angle.

Answer 2

Answer:

122 ° .

Step-by-step explanation:

Let 4th angle be X .

76 ° + 54 ° + 108 ° + x = 360 ° .

238 ° + x = 360 ° .

x = 360 ° - 238 °

x = 122° .

4th angle is 122 ° .
