A square has 2 pairs of parallel lines
Lets try substitution5x+2y=21=5x=21-2y=x=(21-2y)/5
sub into second equation
-2(21-2y)/5+6y=-34(-42+4y)/5+6y=-34solve for yy=-64/17plug into equation and solve for x=(97/17)
Answer:
√2
Step-by-step explanation:
Angle ratio = 45 : 45 : 90
Ratio of side = 1 : 1 : √2
