(trigonometry application)  a hill slopes upward at an angle of 30 digree with the horizontal ground .wath height does a man reach when he has traveled 120 m upward from the foot of hill



Sagot :

The problem looks like this. 

Since we're dealing with an angle, its opposite and hypotenuse, therefore, we should use SINE.

=> sin(angle)=[tex] \frac{opposite}{hypotenuse} [/tex]
=> sin(30)=[tex] \frac{x}{120} [/tex]

Then solve for x. :)
Hint: It is a fraction.
