Solve each triangle using the labels as shown in Illustration 1 (round lengths of sides to three significant digits and angles to the nearest tenth of a degree):

**ILLUSTRATION 1**

To determine

**To calculate:** Each angle and dimension of triangle using the labels as shown in the given figure and the provided data is

**Given Information:**

The given information:

**Formula used:**

The sine rule for triangle is given below as,

**Calculation:**

Consider the give information about the triangle,

Now find the dimensions required by using the law of sine,

As the length of *b* and angle of *B* are given,

Find the length of *a*:

Similarly, find the length of *c*:

First find the angle of *C*, by subtracting the angles of *A* and *B* from

Now, find the length of *c*:
