Answer 1

i need help

Answer 2

With?

Answer 3

Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:

A support structure is shown in which a right triangle PQR is formed with the right angle at Q. The length of PQ is shown as 14 feet, and the length of QR is shown as 6 feet..

Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer, stating the theorem you used. Show all your work. (5 points)

Part B: The length of rod PR is adjusted to 16 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)

Answer 4

Is there a picture?

Answer 5

ya but how do i put pics on here

Answer 6

Save it to your computer, then click Attach File

Answer 8

ok

Answer 9

here

Answer 10

Ok, do you know Pythagorean's Theorem?

Answer 11

i need to be explained to me i have the aweser

Answer 12

plz

Answer 13

Do you know Pythagorean's Theorem?

Answer 14

no i forgot it

Answer 15

\(a^2+b^2=c^2\)

Answer 16

ok

Answer 17

Just substitute in the numbers given.

Answer 18

ok....

Answer 19

\[14^2-6^2=8^2\]

Answer 20

ok....

Answer 21

huh?

Answer 22

No

Answer 23

what do you mean

Answer 24

You are given 14 and 6, where is 8 from?

Answer 25

and it is adding.

Answer 26

that is after i - 14-6

Answer 27

14-6=8

Answer 28

That isn't how it's done.... you have to solve for \(c^2\)

Answer 29

\(14^2 + 6^2 = c^2\), solve for \(c^2\)

Answer 30

how

Answer 31

what is \(14^2\)?

Answer 32

196

Answer 33

what is 6^2?

Answer 34

36

Answer 35

now add those

Answer 36

232

Answer 37

Ok, \(232=c^2\), square root of both sides give \(x=c\)

Answer 38

what

Answer 39

what is the square root of 2323

Answer 40

*232

Answer 41

15.2

Answer 42

yep, so that is all for part a

Answer 43

Ok, now we need to solve for \(a^2 + 14^2 = 16^2\).

Answer 44

ok

Answer 45

@sleepyjess

Answer 46

We know that 14^2 is 196, so what is 16^2?

Answer 47

ok it is 256

Answer 48

196 is 14^2

Answer 49

Ok, so now we have \(a^2+196 = 256\). Subtract 196 from both sides.

Answer 50

196-196=0
256-196=60

Answer 51

Yep, so \(a^2=60\), square root of 60?

Answer 52

7.7

Answer 53

Yes, so a = 7.7

Answer 54

so thats it

Answer 55

Yes

Answer 56

ok thank you
