Question

I WILL FAN AND MEDAL
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

use pythagorean thm since it makes a right triangle
\[PR^2 = 14^2 + 8^2\]

Answer 3

so about 16.12

Answer 4

yes for next part use same theorem, but solve for height
\[17^2 =QR^2 + 14^2\]

Answer 5

9.64?

Answer 6

@dumbcow is that right

Answer 7

need help mi amigo

Answer 8

yes plz
