Question

find the value of X fast plzz and answer should be 100 ​

Answer 1

dcx = 30 + 35 => 65° ( sum of exterior is equal to the opposite interior angles ),

BCD + CDB = X ( SUM OF EXTERIOR ANGLE IS EQUAL TO SUM OF OPPOSITE INTERIOR ANGLES)

= 35 + 65

=> 100°

Answer 2

Answer:

x=100 OK

Step-by-step explanation:

cosdr ABC ,30+35=65,and sum of total interior angl=180 so angl BCA=180-65=115 degree

so angl BCD+ANGL BCA=180 ,straight line

115+BCD=180

bcd=65

exterior angl theorem

x=65+35=100
