Add these angles:

∠DBA + ∠ABF =

∠DBA + ∠DBC + ∠CBE + ∠FBA + ∠EBF =

Answer 1

SoluTion :-

First, we have to find the measures of all the angles.

∠ EBF = 90° (As shown)

∠ CBE - 43° (Given)

∠ DBA = ∠ CBE (Vertically opposite angles)

∠ DBA = 43°

∠ FBA = 90° - ∠ DBA

∠ FBA = 90° - 43°

∠ FBA = 47°

∠ DBC = 360° - (∠ EBF + ∠ CBE + ∠ DBA + ∠ FBA)

∠ DBC = 360° - ( 90° + 43° + 43° + 47°)

∠ DBC = 360° - 223°

∠ DBC = 137°

QuesTion₁

∠ DBA + ∠ ABF

= 43° + 47°

= 90°

QuesTion₂

∠ DBA + ∠ DBC + ∠ CBE + ∠ FBA + ∠ EBF

= 43° + 137° + 43° + 47° + 90°

= 360°
