Question

The measures of three angle of a quadrilateral are 76°,54°and 108°. Find the fourth angle.​

Answer 1

Answer:

forth angle=122 degree

Explanation:

total angle in quadrilateral is 360 degree

so, forth angle= 360- (76+54+108)

                       = 360-238

                       =122 degree

Answer 2

Answer:

Let the fourth angle be x.

76°+54°+108°+x = 360°

238°+x = 360°

x = 360°- 238°

x = 122°

Hence, the fourth angle is of 122°.
