Find the missing sides help with the hypotenuse and legs!!

Step-by-step explanation:

you have right triangle & isosceles

so is 45-90-45

PR^2=PQ^2+QR^2  

c^2=a^2+b^2, where c is the hypotenuse, and a=b

(3)^2=2a^2

18=2a^2

9=a^2

a=3, b=3, both legs are equal to 3

ok

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
