Angle Side Angle theorem (ASA)
We can see that angles BAC and EDF are equal
We can also see that lines AC and DF are equal
And we can see that angles ACB and DFE are equal
Easiest way is algebra so
x+y are 2 numbers
if (x+y)/2=44
and x or y=12 (pic one)
so if x=12
subsitute
(12+y)/2=44
multiply both sdies by 2 to clear fraction
12+y=88
subtract 12 from both sides
y=76
the numbers are 12 and 76
The answer is 3
3x3x3 is 27
Hope this helps
