Question

find the value of x.......

Answer 1

heya...sum of all angles of polygon equals to 360 degrees .....
60 + 50 + 80 +ANGLE ADC equals to 360 degree ....
so ANGLE ADC equals to 170...
so X equals to 360 minus angle ADC ....
==190.....is ans...hope helps u.............___________________________________

Answer 2

Hey !!

This is a four sides bounded fig . polygon
that's why sum of all interior angle =360°

•°•<CBA = 50°
<BCD = 80°
<BAC = 60°
<ADC = ?

since , 50° + 80° + 60° + <ADC = 360°
190° + <ADC = 360°
<ADC = 360° - 190°
<ADC = 170°

Now as we know that angle made by around a point is 360°

so, <ADC + x = 360°
170° + x = 360°
x = 360° - 170°
x = 190° Answer
