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.

Part B: The length of rod PR is adjusted

Answer 1

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.

Answer 2

Use the Pythagoras Theorem
(PR)^2 = 6^2 + 14^2

Answer 3

It cut off that part

Answer 4

Pr is equal to the square root of 52

Answer 5

and for B

Answer 6

not sqrt 52
its sqrt 232
