The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by: cos θ=adjacent/hypotenuse let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have: cos 6=120/h h=120/cos 6 h=120.661 ft Answer: 120.661 ft
To find percent decrease and increase you must subtract the original value (old value) with the new value. Then divide the value you get by the original value and multiply by 100:
165-158 = 7
7÷ 165 × 100 = 4.2424....% or 4.2% rounded to 2 significant figures.
