She needs 4 groups at the most, having 6 kids leftover, 6×4=24, not that hard
Answer:
Step-by-step explanation:
Use the cosine ratio, 
. Insert the values:
Isolate x. Multiply both sides by x:
Divide both sides by cos 25:
Insert into a calculator:
Round to the nearest hundredth:
Done.
ABC = XYZ by SAS
AB = XY - Side
A = X - Angle
So you want to find another congruent <em>side</em>.
Removing the taken possible side, two sides can be congruent.
Either :
BC = YZ
<em>OR</em>
AC = XZ
The answer is x=-7 and x=-1
So you would find out what number in the 9 times tables goes into 25 and there's your answer x
