Answer:
x= 50°
Step-by-step explanation:
if angle A = 25°
then angle D also 25°
angle x = 25+25=50° because the exterior angle of triangle is equal to some of two opposite angles

Answer:
<x=50.
given triangle ACD WITH AC =CD which implies Angle CAD =Angle CDA ( angles opposite to equal sides are also equal )
therefore Angle CAD=angle CDA=25°
now, ANGLE ECA= ANGLE CAD +ANGLE CDA(EXT ANGLE = SUM OF INTERIOR OPPST ANGLES)
therefore angle ECA = 25+25=50°
