A 15 foot ladder leans against the side of a building. If the base of the latter is 6 feet from the bottom of the wall, which expression can be used to find the angle formed by the ladder and the ground.

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

answer: i realy don't get it that much can you me figer it out pleas you
