Question

Solve the Triangle ABC with a= 1, b=2,c=√3​

Answer 1

Step-by-step explanation:

a = 2, b = 1 and c = √3.

So, (a^2) = 4, (b^2) = 1 and (c^2) = 3.

Clearly, (a^2) = (b^2) + (c^2).

Therefore, ABC is a right angled triangle with angle (BAC) = 90°.

So, sin A = 1.

Now, a / (sin A) = b / (sin B) = c / (sin C).

sin B = (1 / 2) and sin C = {(√3) / 2}

Therefore, A = 90°, B = 30° and C = 60°.
