Mary walks a certain distance up a road that climbs a hill. the vertical component of her displacement is 17.63 meters, and the horizontal
component of her displacement is 100 meters. what is the road's approximate angle of inclination?

10 degrees.

Step-by-step explanation:

That would be the angle whose tangent is

17.63 / 100= 0.1763.

That angle is   10 degrees.

29 mil

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
