Question

Law of sines: Sinca) = sin(B) = sin(C)

Answer 1

Answer:

no trangles can be formed

Step-by-step explanation:

We have been given angle A as 75 degrees and sides a = 2 and b = 3.

Using Sine rule, we can set up:

sin(a)                    sin(b)

------------      =       ------------

A                              B

Upon substituting the given values of angle A, and sides a and b, we get:

sin(75)                   sin(B)

------------      =      ------------

2                                3

Upon solving this equation for B, we get:

----->3sin(75)=2sin(B)

----->sin(B)=3sin(75)

                  -------------

                      2

------>sinB=1.4488

Since we know that value of Sine cannot be more than 1. Hence there are no values possible for B.

Hence, the triangle is not possible. Therefore, first choice is correct.
