Question

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:
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 17 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 2

@hanna1 can you help me?

Answer 3

can anyone help?

Answer 4

i cant see the pic.

Answer 5

thats better

Answer 6

A.) 14in because the rods above it are the same size as rod PR, and rod PR is at a slant
B.) i thought it would be 11in but it said round to the nearest hundredth so i dont know this one

Answer 7

what theorem did you use.

Answer 8

ermmmm...

Answer 9

when do u have to turn this in?

Answer 10

@Hero

Answer 11

soon, I have 15 exams/pretests things to do in 3 days. I need to get at lest 6-7 a day.

Answer 12

okay ummm @MARC_D he should be on later but hes really smart and he will help you

Answer 13

ok thanks.

Answer 14

yeah sorry i couldn't help more

Answer 15

In order to find the length of rod PR,you must use pythagores theorem.

Answer 16

For part B,

Answer 17

sketch a right angle triangle using the width of PQ=14 and the hypotenuse of PR=17

Answer 18

Sorry for the late reply...
Hope this helps u...
