The required angles ∡ABF = 110; ∡ABD = 90 ; ∡EBS= 90; ∡FBC =70; ∡DBG= 25
What is angle?
The angle can be defined as the one line inclined over another line.
As given in the question
∡ABF = 110 ;∡EBF = 20
∡ABF-∡EBF = ∡ABE (∡ABE = ∡ABD)
110-20=∡ABD
∡ABD = 90
∡EBC =180 - ∡ABE
∡EBC = 90
∡FBC= ∡ABF - ∡EBF
= 110-20
∡FBC= 70
∡DBG = ∡DBC-∡GBC
∡DBG = 90-65
∡DBG = 25
Thus The required angles ∡ABF = 110; ∡ABD = 90 ; ∡EBS= 90; ∡FBC =70; ∡DBG= 25
