Solve for y, then find the perimeter if PQ=2PS.

y=12/5 and P=120

Step-by-step explanation:

Set (10y-4)=(5y+8) which makes y=12/5

Substitute y in for both PS and QR to get 20 and 20

If PQ=2PS, then 2(20)=40. Do the same for SR to also get 40

40+40+20+20=120

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
