6 9

Answer 1

step by step:
right triangle so use pythagorean theorem
formula is a^2+b^2=c^2
9 is c cause its hypotenuse
so 6^2+b^2=9^2
36+b^2=81
-36 -36
________
b^2=45
b is the sqrt of 45 so about 6.71 so ur right

Answer 2

The square root of 45

Explanation:

9^2-6^2=c^2

81-36=c^2

45=c^2

c=sqrt(45)
