Question

In a triangle ABC, if angle B= 60° and the ratio of two sides is a: C= 2: sqrt3 + 1, then angle A=

Answer 1

I’m pretty sure the answer is 45

Answer 2

Answer:

Well, Your best answer will be is 45° Because, Given two sides and the angle in between,  we can calculate for ∠A using the sine law:

b / sin B = a / sin A

2.45 / sin 60 = 2 / sin A

sin A = 0.707

A = 45˚

Therefore the answer is letter A: 45 Good Luck!
