Answer 2

Answer:

in 1st que

In triangleABC

angle CAB+DAC=180

angle CAB=180-107=73 (linear pair)

SUM OF ALL ANGLE OF TRIANGLE =180

X+57+73=180

x=180-(57+73)

x=180-130

x=50degree

in 2nd que

SUM OF ALL ANGLE OF TRIANGLE =180

X+105+40=180

angle x=180-(40+105)

x=180-145

x=35degree

x+y+65=180 (linear pair )

y=180-(65+35)

y=180-100

y=80degree

HOPE THIS HELPS!
