In ΔABC\Delta ABC, if ∠A=45∘,∠B=75∘\angle A = 45\mathrm{^\circ },\angle B = 75\mathrm{^\circ }, then a+c2a + c\sqrt 2 is equal to
View answer and explanation
Correct option: D
2b2b
Option D (2b2b) is correct because, using the sine rule and given angles, the expression a+c2a + c\sqrt{2} simplifies to 2b2b.
