A plane rises from take-off and flies at an angle of 4° with the horizontal runway. When it has gained 850 feet, find the distance, to the nearest foot, the plane has flown.
B
c=?
850 ft

The plane has flown approximately
how many feet? (Round to the nearest foot.)

true

explanation:

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

0,0
