Answer 1

ΔABC ~ ΔDEF ⇒

a)

∢A = ∢D = 39°

∢B ≡ ∢E = 73°

∢C ≡ ∢F

⇒

∢D + ∢E + ∢F = 180°

39° + 73° + ∢F = 180°

$\implies \measuredangle F= 180^{0} - 112^{0} = 68^{0}$

b)

∢A ≡ ∢D

∢B = ∢E = 27°

∢C = ∢F = 62°

⇒

∢A + ∢B + ∢C = 180°

∢A + 27° + 62° = 180°

$\implies \measuredangle A = 180^{0} - 89^{0} = 91^{0}$
