Answer:
A. 16.12 ft B. 9.64 ft
Step-by-step explanation:
For both of these, you need Pythagorean's Theorem because we have right triangles. In part A, we are given 2 legs and are asked to find the length of the hypotenuse:
[tex]14^2+8^2=PR^2[/tex] and
[tex]196+64=PR^2[/tex]
and PR = 16.12 ft
In part B, we are given the length of the hypotenuse and side PQ remains the same:
[tex]14^2+QR^2=17^2[/tex] and
[tex]196+QR^2=289[/tex]
[tex]QR^2=289-196[/tex] so
QR = 9.64 ft
