Question

the measure of three angles of quadrilateral is 30 degree 70 degree and hundred degree find out the measurement of fourth angle​

Answer 1

Using angle sum property
We get
30+70+100+x=360
x=160

Answer 2

Answer:

First angle = 30°

Second angle = 70°

Third angle = 100°

Fourth angle = x

Sum of interior angle of a quadrilateral = 360°

30° + 70° + 100° + x = 360°

200° + x = 360°

x = 360° - 200°

x = 160°

Fourth angle is 160°
