Combining your skills with similar triangles, trigonometry and the Pythagorean Theorem, you are ready to tackle problems that are connected to more real world scenarios. The situations you will be examining will be specifically related to right triangles, and you will be Solving for Sides or Solving for Angles by using trigonometric functions.
Combining your skills with similar triangles, trigonometry and the Pythagorean Theorem, you are ready to tackle problems that are connected to more real world scenarios. The situations you will be examining will be specifically related to right triangles, and you will be Solving for Sides or Solving for Angles by using trigonometric functions.
For example: with angles of elevation, if two of the sides of the right triangle are known, then the formula for the angle of depression is given as below:
Tan θ =Opposite Side/Adjacent Side
or
θ = tan-1 (Opposite Side/Adjacent Side)
<u>'''Problem'''</u> - 1.The angle of elevation of the top of a tower from a point on the ground, which is 30 m away from the foot of the tower, is 30°. Find the height of the tower?
