Answer:
The length of a side of the flag is 7.2inches
Step-by-step explanation:
Let length = x
Let hypotenuse = x+3
UsingPythagoras'Theorem:
x^2 + x^2 = (x+3)^2
x^2 + x^2 = x^2 + 6x + 9
2x^2 = x^2 + 6x + 9
×^2 - 6x - 9 = 0
x=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)
×=[6+sqrt.72]/2
×=7.2inches
×=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)
x=[6-sqrt.72]/2
×=-1.2(rej)
(PS.sqrt is square root)

Answer:
7.2 in
Step-by-step explanation:
Let length of side of flag=x
Hypotenuse of right triangle=x+3
According to question information
Using Pythagoras theorem
Using identity:
Using quadratic formula :
It is not possible because the length of side is always positive.
Hence, the side of flag=7.2 in
36-7=29
