Two farmers each have triangular plots of land in the diagram below with approximate values shown for lengths in feet
Ray Of Light [21]

Answer:

  • a) Plots are similar
  • b) x= 5577 feet

Step-by-step explanation:

<em>Refer to attached</em>

<h3>Question</h3>
  • a) Are the plots of land similar?  
  • b) Find to the exact value of x and rounded to the nearest tenth?
<h3>Solution</h3>

The small triangle have missing angle of 180° - (52° + 58°) = 70°

This is indicating both triangles have same 3 angle measures.

Since all angles are same, the triangles are similar.

<u>Corresponding sides, against corresponding angles are:</u>

  • 6180 and 8240
  • x and 7436

<u>As per property of similarity, the ratio of corresponding sides is same</u>

  • 6180/8240 = x/7436
  • x = 6180*7436/8240
  • x = 5577 feet

Someone please help me with this asap
Leokris [45]

Answer:

All of these terms are dollar amounts.

Step-by-step explanation:

Here, x + y = 10 (where these numerals represent counts)

(1/2)x + (1/4)y = 4 (where (1/2), (1/4) and 4 are dollar amounts)

Let's eliminate y.  To accomplish this, mult. the 2nd eq'n by-4, obtaining

-2x - y = -16, and then combining this with the 1st equation, as follows:

-2x - y = -16

  x + y = 10

-------------------

 -x  = -6, or x = 6.  This represents the number of pens purchased by Terrance.  

Subbing 6 for x in the first equation, we get y = 4.  This represents the number of pencils he bought.

($0.50)x + ($0.25)y = $4.00 (dollar amounts)
