Question

find x in the figure​

Answer 1

Answer:

angle A =angle D

therefore angle D= 52°

the sum of total of all angle of triangle is 180 °

so 52+40+x =180

92+x= 180

x=180-92

88 =x

Answer 2

Answer:

if AB is Parallel to DC,

angle ADC=52°

therefore ,52° + x + 40° = 180° (angle sum property)

x = 180 - (52+40) =180 - 92

x = 88°
