Aright triangle abc is similar to triangle pqr such that the hypotenuse bc=10 and the hypotenuse qr=4. if ac=8, then what is the length of pr? round your answer to the nearest tenth.

PR = 3.2

Step-by-step explanation:

We can use proportions to solve this problem.  Put the first triangle side over the second triangle side.

BC           AC

=

QR            PR

Substituting in values

10          8

=

4            PR

Using cross products

10 PR = 8*4

10 PR = 32

Divide by 10

10 PR/10 = 32/10

PR = 3.2

70,000 + 6,000 + 800 + 30

step-by-step explanation:

i think it might be a but you might want a second opinion
