In a region of mixed farming, farms keep pigs, cattle or
sheep. there are 77 farms altogether. 19 farms keep only
pigs, 8 keep only cattle and 13 keep only sheep. 13 keep
both pigs and cattle, 28 keep both cattle and sheep and 8
keep both pigs and sheep.
a) draw a venn diagram to show the above information.
b) calculate n(pncns).

answer: we have from thales theorem that because the 2 triangles are similar, jm/jk=jn/jl. we have that jn=x, jl=x+24 and that jm=7 and jk=28. substituting, we get:

x/(x+24)=7/28.

hence, x/(x+24)=1/4. this leads to 4x=x+24, 3x=24, x=8. we have solved for x=jn and this is equal to 8.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
