I need help, due in 10 minutes!!! best answer gets brainliest, thanks <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)

Step-by-step explanation:

a:If you know the lengths of the two legs of a right triangle, use the PYthagorean theorem to get the length of the hypotenuse (side opposite the right angle). That's √(14² + 9²) = √(196 + 81) = √277 = about 16.64 ft

on b you are given the hypotenuse and one leg so you use the same theorem, just with subtract instead of add:

√(18² - 14² ) = √(324 - 196) = √128 or about 11.31 ft Hope i helped!!!

answer: sine

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
