The value of b or measure of the side length is 38.05 units after applying the sin law in the triangle.
What is the triangle?
In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture with dimensions and angle
As we know in the triangle we can apply the sin law if the sides or angles are known to find the remaining unknown values.
The measure of the angle B = 180 - 31.6 - 38
The angle B = 110.4 degrees
Applying sin law in the triangle:
b/sinB = BC/sinA
b/sin110.4 = 25/sin38
b/sin110.4 = 40.60
b = (sin110.4)40.60
b = 38.05 units
Thus, the value of b or measure of the side length is 38.05 units after applying the sin law in the triangle.
