let W={x:x is a whole number less than 15} Y={x:x is even natural number less than 20} then find a. all elements of sets W and Y b. W U Y c. W n Y

susie has 7 apples

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

its line 2 i just added the rest or else it wouldn't let me answer
