Question

find. x in following figure​

Answer 1

Answer:

100°

Step-by-step explanation:

sum of all angles of a quadrilateral is 360°

so

110+90+60+x = 360

260+x = 360

x = 100°

Answer 2

We know that sum of all angles in a quadrilateral is 360°.

So, we have 3 angles and have to find out the 4th angle.

360 = 110 + 60 + 90 + X

360 = 260 + X

360 - 260 = X

100 = X

So, X = 100°
