You can do 5+5+10, 6+6+8, 9+9+2, 4+4+12, 3+3+14, 2+2+16, 1+1+18. I believe these are all of them, so there are 7 ways.
Congruent means Same Side, Same Shape.
If two angles are congruent, they are to be of the same size and same shape or a fraction of it (Dilation)
Y^2 -11y = 0
We can factor it:
y * (y -11) = 0
So y = 11, 0
25^2-13^2=456
456 square root is 21.354...
21
Answer:
7 1/8
Step-by-step explanation:
Assuming that the first 13 was a mistake then the equation would be 13 1/2 + 2n = 27 3/4
subtrace 13 1/2 from 27 3/4
14 1/4
divide by 2
7 1/8
