Step-by-step explanation:

The picture of the question in the attached figure

we know that

In the right triangle of the figure

----> by SOH (opposite side divided by the hypotenuse)

using a calculator

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

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
