Experts:

Based on known information of a “triangle”, I need some assistance with calculating distances (through MS-Excel).

Please see attached Word document that provides more details for the problem(s). Here's what the documents contains:

Page 1: I'm using MS-Excel to calculate distances (i.e., triangle sides as well as chords). Problem on page 1 illustrates the process for 2 calculations (1a and 1b; 1c summarizes the values/information).

Page 2: For problems 2a and 2b, the triangles changed from a "right triangle" to a "non-right triangle". I'm requesting additional information/guidance as to how I should modify the Excel calculations from [e.g., = 2 * r * SIN (degrees / 2 * PI() / 180)] to ???

That is, the two specific questions I need assistance with are:

Problem 2a-1: What is the length of side B (it should be less than 4.1)?

Problem 2a-2: What is the length of chord (given change from 90 degrees – sides B and C – to 100 degrees)?

Problem 2b-1: What is the length of side B (it should be greater than 4.1)?

If needed, I can provide the XLS that includes the calculations for problem #1.

Thank you in advance,

EEH
