Question

A portion of a hiking trail slopes downward at about an 84° angle. To the nearest tenth of a foot, what is the value of x, the distance the hiker traveled along the path, if he has traveled a horizontal distance of 120 feet? B 849 А 120 ft С O A. 12.5 ft B. 130.2 ft C. 143.3 ft O D. 120.7 ft

Answer 1

The given figure form a triange right angled at A.

AC=120 ft.

BC=x.

BC is the hypotenuse.

Now, applying trigonometric property in the triangle,

Therefore, the value of x is 120.7 ft.
