A section of a highway is constructed with a 11% grade. What angle does the highway make with a horizontal line? Round to the nearest hundredth of a degree. m∠A ≈ 84.81°
m∠A ≈ 83.72°
m∠A ≈ 6.28°
m∠A ≈ 5.19°

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
