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 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)

A. PR = 15.23 ft

B. QR = 7.75 ft

Step-by-step explanation:

Part A:

In the case of a right triangle, by the pythagorean theorem we can calculate the hypotenuse (the side opposite the right angle) which, in this case, is the missing side PR, as we can see in the graph. So,

PQ = 14 ft

QR = 6 ft

Part B:

Applying the Pythagorean Theorem again, the leg or QR side is found.

PR = 16 ft

PQ = 14 ft

Isolating QR, we have

Hope this helps!

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
