A water tower has a shadow 42.5m long. An upright meter stick has a shadow 0.7m long at this time. What is the height of the water tower rounded to the nearest meter?

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

y - 25 = 2 ( x - 10 ) should be the answer
