Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
Point (2, 1)
Point (6, 7)
<u>Step 2: Find distance </u><em><u>d</u></em>
Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>
- Substitute in points [Distance Formula]:

- [√Radical] (Parenthesis) Subtract:

- [√Radical] Evaluate exponents:

- [√Radical] Add:

- [√Radical] Simplify:

we can get z because every straight line is 180 degrees, and 180-122= 58 degrees for z
we can then get y with that same routine, 180-58= 122 degrees for y
lastly, using those steps again, we know x is 58 degrees
