Question

Solve for the missing distance.

  1. 18.9 meters
  2. 19.5 meters
  3. 47.2 meters
  4. 27.5 meters

hintHint:

sin space theta equals fraction numerator p e r p e n d i c u l a r over denominator h y p o t e n u s e end fraction

The correct answer is: 18.9 meters


    Here d is the perpendicular and 30 meters is the hypotenuse.
    sin space 39 equals d over 30
equals greater than d equals sin space 39 cross times 30
equals greater than d equals 18.8796
    The missed distance is 18.9 meters.

    Know how  to find the perpendicular ,hypotenuse and base for the respective angle
