  • 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

The width of a rectangle is 6 less than half the length. If x represents the length, which equation could be used to find the wi
Shtirlitz [24]

Answer:

C. y=1/2x-6

Step-by-step explanation:

The correct answer is C. y=1/2x-6.

If we are finding 1/2 of the length, and the length is represented by x, than we would have 1/2x.

It also says 6 less than halve of the length, so we would represent that as 1/2x-6, and that shows us the proper equation to find the width.

Hope this helps!
