Question

In the following figure, if m(are DXE) = 90° and m(are AYC) = 30°. Find ∠DBE.

Solution

By inscribed angle theorem,

m∠AEB=(1/2) × m∠AYC=(1/2) × 30o = 15...(1)

m∠EAD=(1/2) × m∠DXE=(1/2) × 90o = 45o ...(2)

∠DBE + ∠AEB = ∠EAD

⇒ m∠DBE + 15o = 45o

⇒ m∠DBE = 45o - 15o = 30o

  Is there an error in this question or solution?
