Solve the problem below:
1. From an airplane at an altitude of 1,500m the angle of depression to a rock on the ground measures 29°. Determine the distance from the plane to the rock.


Sagot :

first: make a sketch or drawing of your question
second : label the given value of a each part
third:  form it a right triangle
 
1500 = which is the height of of a right triangle
29° = the angle of depression of the triangle 
  then you can be able to solve the distance between the plane and the rock by using the SOH CAH TOA . in this case we used the TOA.

tan 29° =opposite/ 1500
opposite or the distance = 831. 46 (rounded off to the nearest hundredths)
