I think the answer is 5 because 25 divided by 5=5
angles EFH and GFH are congruents
for the second equivalence criterion two triangles are equivalents if they have respectively 2 angles and 1 side congruents
the two triangles have congruents the angle right angle (HGF and HEF) and the 55 degrees angles (EFH and GFH); then they have in common the HF side.
so the triangles are congruent and so all the sides are respectively congruent,for example EH with HG:
EH=HG
s+36=7s
s+36-7s=0
s-7s=-36
-6s=-36
6s=36
s=6
<em>sorry for my english</em>
I think the straw can hold about 15000 mm^3.
3.c - 8 = 5
(3.c - product of 3 and a number)
(-8 : 8 less)
3) Equation is y=10x
x. y
1. 10
2. 20
3. 30
4. 40
I'm sorry I don't get number 4
