Atriangle with sides 40 feet 50 feet and 60 feet . on a drawing 1 inch equals 10 feet how long are the sides of the triangle on the drawing

40/10=4

50/10=5

60/10=6

the triangle of the drawing has sides of 4 inch 5 inch and 6 inch

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
