Question

3 angle of quadrilateral are 110 degree 68 degree 82 degree respectively find the fourth angle

Answer 1

Hi Friend ✋✋

Sum of all Four angles of a quadrilateral is 360°

then let us take <A = 110°
<B = 68°
<C = 82°
<D = x = ?

then

360° = <A + <B + <C + <D

360° = 110° + 68° + 82° + x

360° = 260° + x

x = 360° - 260°

x = 100°

The fourth angle is 100°

Hope it helps.....

Answer 2

given 68+82+110+x = 360
x + 260 = 360
x = 100
so fourth angle of quadrilateral is 100 degrees
