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

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
