Step-by-step explanation:

Step-by-step explanation:

a=side of right triangle

b=side of right triangle

c=hypotenuse

the solution is h=10 because you add 9 to each side of the equation.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
