In the diagram below, PQ is parallel to MN . If MP=25, PQ=18, and MN=33, find the length of PO . Figures are not necessarily dra
Ray Of Light [21]

Given that triangles MON and POQ are similar triangles, the length of PO is 30 units.

<h3>What are Similar Triangles?</h3>

The triangles that are similar to each other will have their corresponding sides proportional to each other.

Given:

MP = 25

PQ = 18

MN = 33

Triangles MON and POQ are similar triangles.

Let PO = x

Therefore:

MN/PQ = MO/PO

Substitute

33/18 = (25 + x)/x

Cross multiply

33x = 18(25 + x)

33x = 450 + 18x

33x - 18x = 450

15x = 450

x = 30

Therefore, given that triangles MON and POQ are similar triangles, the length of PO is 30 units.

A new Community Sport complex is being built in safe harbor the perimeter of the rectangular playing field is 402 yards the leng
ivanzaharov [21]

Answer:

<h2>length = 159 yards</h2><h2>width = 42 yards</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 402 yards

The statement

the length of the field is 9 yards less than quadruple the width is written as

l = 4w - 9

Substitute this is expression into the above formula and solve for the width

That's

402 = 2( 4w - 9) + 2w

402 = 8w - 18 + 2w

10w = 402 + 18

10w = 420

Divide both sides by 10

<h3>w = 42</h3>

Substitute this value into l = 4w - 9

That's

l = 4(42) - 9

l = 168 - 9

<h3>l = 159</h3>

Therefore

length = 159 yards

width = 42 yards

Hope this helps you
