Question

find the x value in the figure​

Answer 1

Answer:

30

Step-by-step explanation:

It is given as 80 for one traingle and remain is 100 since for the line it is 180 degrees

so 100 +50=150

sum of angles of triangle is 180 therefore x=30

Answer 2

Step-by-step explanation:

/_ADC+/_CDB=180°

80°+CDB=180°

CDB=180°-80°

CDB=100°

now ∆BDC

CDB+CBD+DCB=180°

100°+x+50°=180°

x=180°-150°

x=30°
