Answer:

20 inches

Step-by-step explanation:

Use the Pythagorean Theorem.

a^2 + b^2 = c^2\\15^2 + b^2 = 25^2\\225 + b^2 = 625\\b^2 = 400\\b = \sqrt{400} \\b = 20

What is the perimeter of RSTUV?
MrMuchimi

Answer:

this should be 132 units   i hope this helps!   :)

Step-by-step explanation:

so these figures are similar

we are given 3 side measurements on one, and 3 on the other

we know that side BA is 10 units, and that SR which is the same side, is 14 units

we can conclude that they added 4 units to this side

so with the other side lengths that we are given we can figure out what the length of the perimeter of RSTUV is

10 + 4 = 14

15 + 4 = 19

28 - 4 = 24  

42 - 4 = 38

25 + 4 = 29

42 TU

28 UV

19 VR

14 SR

29 ST

add all the side together to get 132 units
