Find the missing length of the following trapezoid

Mathematics
1 answer:
Schach [20]3 years ago
4 0

Answer:

1) The length of DC is 20.

2) The length of PS is 17.

Step-by-step explanation:

1) If DR = RE and CS = SB, then we can use the following proportionality ratio:

\frac{DE}{DR} = \frac{32 - x}{26 - x} (1)

Where x is the length of segment \overline{CD}.

If DE = 2\cdot DR, then the value of x is:

2 = \frac{32-x}{26-x}

52 - 2\cdot x = 32 - x

20 = x

The length of DC is 20.

2) If QV = VP and RW = WS, then we can use the following proportionality ratio:

\frac{QP}{QV} =  \frac{x-7}{12-7} (2)

Where x is the length of segment \overline{PS}.

If QP = 2\cdot QV, then the value of x is:

2 = \frac{x-7}{5}

10 = x-7

x = 17

The length of PS is 17.

Does anyone know how to find this I'm studying and me and my family don't understand! I only need help on #17
avanturin [10]

Answer:

<u>4</u>

Step-by-step explanation:

Hi so basically you just convert the inches to decimals so

0.5 x 0.5 x 0.25 = 0.0625

Use a calculator to convert 0.0625 into fraction which is \frac{1}{16}

Multiply \frac{1}{4} by 3 = \frac{1}{64}

Then multiply \frac{1}{16} by \frac{1}{64} = 4

Soo that was probably very confusing, but I hope it helps! :)

Plz click the Thanks button, I rrly appreciate it!
