Simplify:

√(61-24√5)

3√(5) - 4

Step-by-step explanation:

a^2 - 2ab +b^2 = (a-b)^2

√(61-24√5)

= √((4-3√5)^2)

=3√(5) - 4

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

wait nvm i know the correct answer now its 100%   81 square feet
