Question

In ∆ACD,CA=CD. find x​

Answer 1

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 2

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°
