Solving Right Triangles
The preceding formula returns radians. To convert to degrees, use this formula:
=DEGREES(ATAN(height/base))
If you know the height and base, you can use the following formula to calculate the angle formed
by the hypotenuse and height (angle B):
=PI()/2–ATAN(height/base)
The preceding formula returns radians. To convert to degrees, use this formula:
=90–DEGREES(ATAN(height/base))
The companion CD-ROM contains a workbook, solve right triangle.xlsm , with
formulas that calculate various parts of a right triangle, given two known parts. These
formulas give you some insight on working with right triangles. The workbook uses a
simple VBA macro to enable you to specify the known parts of the triangle.
Figure 10-2 shows a workbook containing formulas to calculate the various parts of a right triangle.
