Answer 1

ΔABC ~ ΔDEF ⇒

a)

∢A = ∢D = 35°

∢B ≡ ∢E = 75°

∢C ≡ ∢F

⇒

∢D + ∢E + ∢F = 180°

35° + 75° + ∢F = 180°

$\implies \measuredangle F= 180^{0} - 110^{0} = 70^{0}$

b)

∢A ≡ ∢D

∢B = ∢E = 40°

∢C = ∢F = 53°

⇒

∢A + ∢B + ∢C = 180°

∢A + 40° + 53° = 180°

$\implies \measuredangle A = 180^{0} - 93^{0} = 87^{0}$
