Help!? Helping my son with geometry ... I have no clue what I’m doing here
Tatiana [17]

<u>We are Given:</u>

∠1 = 65°

<h3><u>Finding the measure of all other angles with proof:</u></h3>

<u>∠2:</u>

∠1 + ∠2 = 180°           <em>(angle 1 and 2 form a Linear Pair)</em>

65 + ∠2 = 180            <em>(Angle 1 = 65°)</em>

∠2 = 180 - 65

∠2 = 115°

<u>∠3:</u>

∠1  = ∠3            <em>(Angle 1 and 3 are vertically opposite)</em>

65 = ∠3             <em>(Angle 1 = 65°)</em>

<em>∠3 = 65°</em>

<em />

<u><em>∠4:</em></u>

∠4 = ∠2                  <em>(Vertically opposite angles)</em>

∠4 = 115°                <em>(∠2 = 115°)</em>

<u><em /></u>

<u>∠5:</u>

∠5 = ∠1          <em>(Corresponding angles)</em>

∠5 = 65°        <em>(∠1 = 65°)</em>

<u><em /></u>

<u>∠6:</u>

∠6 = ∠2      <em>(Corresponding angles)</em>

∠6 = 115°    <em>(∠2 = 115°)</em>

<em />

<u>∠7:</u>

∠7 = ∠3        <em>(Corresponding Angles)</em>

∠7 = 65°       <em>(∠3 = 65°)</em>

<em />

<u>∠8:</u>

∠8 = ∠4        <em>(Corresponding angles)</em>

∠8 = 115°      <em>(∠4 = 115°)</em>

Answer: 14.48000 . . . ≤ t < 15.0000

Step-by-step explanation:

"Truncated by a hundreths of a second" means that the time was rounded to the nearest 0.0X second.  That would mean the reported time of 14.48 seconds was shortened from a time period having more digits to the right.  For example, If the time were actually 14.48223 seconds, the time was truncated to just 14.48 seconds.  The term used here. truncated, means that the digits after the hunredth place are simply dropped.  It doesn't say rounded, just truncated.  Brutal.  So that would mean that times between 14.48000 . . . and 14.48999 . . . would all be reported as 14.48 seconds.

So the time could actually be 14.48000 . . . ≤ t < 15.0000
