Question

The shadow of a vertical tower is 40.6 meters long when the angle of the elevation of the sun is 34.6 degrees.  find the height of the tower.

A plane flies on a bearing of 230 degrees at 350 MPH.  a wind is blowing from the west at 30 MPH.  find the ground speed and the final bearing of the plane in the wind.

Answer 1

me assume "sun angel" is from horizontal up tu sum=at base av triangel

then, shado leng=base av rite triangel with angel=34.6 deg

tower hite=40.6* tangent(34.6 deg)

=40.6*0.689853791

=28
