Question

In this Figure,Seg BD is congruent to seg AD,Seg EC is congruent to seg EB, measurement of angle BED= 60°,Angle BDA is right angle,then Find measurement of Angle ABC​

Answer 1

Answer:

105

Step-by-step explanation:

It's a pretty simple question, but looks complicated

Lets find the angle ABC by finding angle ABD, DBE, EBC and then add them

angle ABD=(180-90)/2=90/2=45

angle DBE=(180-90-60)=30

Before knowing angle EBC, lets know angle BEC

angle BEC=180-60 (linear pair)  =120

Now, angle EBC=(180-120)/2=60/2=30

So angle ABC= 45+30+30=105 degree
