Question

can someone explain this?!

Answer 1

Answer:angle abe+ angle ABC

90 +45

135 is the answer.......

Answer 2

ang ABE= 90° (ABED is a square)

BE=EC (given)

: . ang CBE = ang ECB let it be x

ang BEC= 90° ( DEB= 90° )

so, x+x+90°=180°

2x=90°

x=45°

ang ABC= ang ABE+ ang EBC

= 90°+x

= 90°+ 45°

= 135°

Hope it helps you..
