In a cyclic quadrilateral ABCD, AD is parallel to BC. The bisector
of <BAD meets BC at E and the circle at F. Prove that:
EF=FC ( BF - DF

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
