Agraphic artists tools include a 30°,60°,90° triangle. the hypotenuse of the triangle has a length of 10inches. to the neareet inch, how long are the legs of the triangle?

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,
