Option B. 1

Step-by-step explanation:

We have

Two side lengths of a triangle of 10 cm and 8 cm, and the angle between the sides of the triangle measures 40°

so

Applying the law of cosines find out the length of the third side

Let

c ----> the length of the third side of triangle

so

The measurements of the three sides of the triangle are unique

therefore

Using these measurements, only one triangle can be constructed
