Question

Find each measurement indicated. Round your answer to the nearest tenth.

Answer 1

The measure of the angle B is 30 degree after applying the sin law of triangle.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle shown in the picture:

We can apply the sin law of the triangle to find the angle B

$\rm \dfrac{28}{sin91} =\dfrac{14}{sinB}$

SinB = 0.499

B  = 29.99 ≈ 30 degree

Thus, the measure of the angle B is 30 degree after applying the sin law of triangle.
