P=45
How do I Know that?
<em>I added 35+100 and that equal to 180, so Then I subtracted 180-135 and that gave me 45. So P=35. Add all of them up to see if it = 180 and if it does, then your answer is correct. remeber 3 angles of a triangle =180.</em>

Hope I could help!
duh obviously the answer is idk, and let me tell you why
Step-by-step explanation:
because when you add 2+4 and then it gives you 78 now you can square root that 78 and it will give you 8 and after that you get 8 of your fingers and play with yourself a little bit but not too much, therefore the answer is idk.

AC = 39
Side Am/mB (x + 1)/(2x - 5)
Side Am/mC (x + 21)/(2x + 21)
m is the point where the parallel line is.
AB = AC
(x+1)/(2x -5) =(x +21)/(2x+21)
Cross multiply.
(x+1)(2x+21)=(2x-5)(x+21)
2x^2+23x+21=2x^2+37x-105
Subtract 2x^2 from both sides.
23x+21=37x-105
Subtract 23x from both sides.
21= 14x -105
Add 105 to both sides
126 = 14x
Divide both sides by 14
x = 9
Plug 9 back in for x in
2x + 21
2(9) + 21 = 39
