HELP! BRAINLIST COULD GET 50+ POINTS!!!

Answer 1

Answer:

B

Step-by-step explanation:

well by rotating  ΔABC  by 60*(degrees) about A , such that in ΔA'B'C,B =C'

you can see that ΔAPP' is equilateral side length 1, meaning that <APP' =60*

you can also see that ΔCPP' is a 30- 60- 90 right angle also meaning that <CPP' =60* now,by adding the two together you see that < ACP =120* now you can also use the law of cosins and soooo

                          s2=(AP)2+(CP)2-2(AP)(CP)cos120*

                                     s2=1+4-2(1)(2)cos120*

                                             s2=5-4 (-1over2)

                                                      s=$\sqrt{x} 5+2$

                                                    7

so b is your answer hope this helped
