Three times a number r plus 8 is fewer than -12

Step-by-step explanation:

3 × (r + 8) < 12

3r + 24 < 12

subtract 24 from each side

3r < -12

divide each side by 3

r < -1

c is the final answer! : )

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,
