Let the supplementary angle = $$ heta$$ Required angle = $$(frac{1}{3} heta)$$ Sum of an angle and its supplementary angle = 180° => $$ heta + (frac{1}{3} heta) = 180$$° => $$frac{4}{3} heta = 180$$° => $$ heta = frac{180 imes 3}{4} = 135$$° $$ herefore$$ Measure of the angle = $$frac{1}{3} imes 135 = 45$$° => Ans - (A)
