Answer:

∠B = 19°

Step-by-step explanation:

In the triangle ABC,

                       ∠A = 120° side a = 8 and b = 3

We have to find angle B.

We will apply sine rule in this triangle

\frac{a}{sinA}=\frac{b}{sinB}

\frac{8}{sin120*}=\frac{3}{sinB}

8 sin B = 3 sin 120°

Sin b = \frac{3}{8} (sin 120°) =  \frac{3\times 0.866}{8} = 0.3248

B = sin⁻¹ (0.3248)

  = 18.95 ≈ 19°

Therefore, ∠B = 19° is the answer.

What multiplies to 378 and adds to -51
Oliga [24]
Your answer would be -9 & -42. 

Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.

Hope this makes sense & helps you ! (:
