In the figure, P'Q = (46 +a - 2) cm, QR-(4a - b - 4) cm and PR = (2a - 3b +8) cm. Find the perimeter in terms of a and b.
(a)
(b) Given that PQR is an equilateral triangle and the perimeter of
2
*PQR is 30 cm, find the values of a and b.

the answer is 288..

hope this

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
