Using the distance formula, find the distance between these two points. Round to the nearest tenth. (8,9) and (3,2)
Masja [62]

Answer:

The answer is

<h2>8.6 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(8,9) and (3,2)

The distance between them is

d =  \sqrt{( {8 - 3})^{2}  + ( {9 - 2})^{2} }  \\  =  \sqrt{ {5}^{2}  +  {7}^{2} }  \\  =  \sqrt{25 + 49}  \\  =  \sqrt{74}  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \\  = 8.60232...

We have the final answer as

<h3>8.6 units to the nearest tenth</h3>

Hope this helps you

Plz help me with my geometry asap 50 pts and brainliest NO SCAMMING OR I WILL REPORT
bearhunter [10]

Step-by-step explanation:

1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.

2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)

3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)

4. that means that ΔADB ≅ΔCDB via SSS rule.

5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)

Hope this helps! :)
