The equations in this system were added to solve for y. What is the value of y?

x + 6 y = 10. Minus x + 3 y = negative 15. Equals 9 y = negative 5.
y = Negative StartFraction 9 Over 5 EndFraction
y = Negative StartFraction 5 Over 9 EndFraction
y = StartFraction 5 Over 9 EndFraction
y = StartFraction 9 Over 5 EndFraction

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

other answer is correct. i had used the radius of the radius somehow. a website:
