Setting the angle measure

Make sure that your angle measure mode is appropriate. By default, the app starts in degree mode. If the

angle information you have is in radians and your current angle measure mode is degrees, change the mode

to degrees before running the solver. Tap or depending on the mode you want. (The

button is a toggle button.)

NOTE: The lengths of the sides are labeled a, b, and c, and the angles are labeled A, B, and, C. It is important

that you enter the known values in the appropriate elds. In our example, the length of two sides and the

angle at which those sides meet is known. Therefore, if you specify the lengths of sides a and b, you must

enter the angle as C (since C is the angle where A and B meet). If instead you entered the lengths as b and c,

you would need to specify the angle as A. The calculator display helps you determine where to enter the

known values.

Specify the known values

▲

Go to a eld whose value you know, enter the value and either tap or press .

Repeat for each known value.

In the a box, enter 4 and then press .

In the b box, enter 6 and then press .

In the C box, enter 30 and then press .
