I think the answer would be B. 4 cm
X/32.1 = 25/53.5
x = 25/53.5 × 32.1
x = 5/10.7 × 32.1
x = 15
The longest side of second garden is 15 feet
First solve the congruence 
. Euclid's algorithm shows
330 = 25 * 13 + 5
13 = 2 * 5 + 3
5 = 1 * 3 + 2
3 = 1 * 2 + 1
=> 1 = 127 * 13 - 5 * 330
=> 127 * 13 = 1 mod 330
so that 
is the inverse of 13 modulo 330. Then in the original congruence, multiplying both sides by 127 twice gives
Then any integer of the form 
is a solution to the congruence, where 
is any integer.
Vertical: p and r; s and q
Supplementary: p and s; p and q; q and r; r and s
Adjacent: same as supplementary
Answer: b=31, c=5
Step-by-step explanation: if this is a equilateral triangle then all the sides when split in half will be the same as the other side
