Step-by-step explanation:
Absolute value -9 is 9, but there is a negative sign so it is -9
-9=-9
Greater than or equal to works because of the equal sign.
Less than or equal to also works because of the equal sign.
The measure of the angle B is 30 degree after applying the sin law of triangle.
<h3>What is the triangle?</h3>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
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.
