5[ a ] a:5 is listed in the top left corner of the display.

3[ b ] b:3 is listed in the top left corner of the display.

5[ c ] c:5 is listed in the top left corner of the display.

To solve for the angles use:

„[ α ] Calculator reports

Solving for α, and shows the result α:

72.5423968763

Note: If you get a value that is larger than 180, try the following:

10[ α ] Re-initialize a to a smaller value.

„ [ α ] Calculator reports Solving for α

Next, we calculate the other two values:

„ [ β ] The result is β:

34.9152062474 .

„ [ γ ] The result is γ:

72.5423968763.

You should have the values of the three angles listed in stack levels 3 through

1. Press + twice to check that they add indeed to 180

Press L to move to the next variables menu. To calculate the area use:

„[ A ]. The calculator first solves for all the other variables, and then

finds the area as A:

7.15454401063.

Note: When a solution is found, the calculator reports the conditions for the

solution as either Zero, or Sign Reversal. Other messages may occur if the

calculator has difficulties finding a solution.

Pressing „@@ALL@@ will solve for all the variables, temporarily showing the

intermediate results. Press ‚@@ALL@@ to see the solutions:
