A master painter can paint 110 square yards of surface area with a roller in 1 hour, while his apprentice [a person who is learning] can paint 85 square feet of surface area per hour with a brush. The master painter asked his apprentice to paint a surface area of 5,100 square feet. The apprentice paints for 5.5 hours. After 5.5 hours, how many square feet does the apprentice have left to paint?

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,

the answer is 48m^2!

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
