Question

What is the length of side x?

  1. 6.57 cm
  2. 7 cm
  3. 7.44 cm
  4. 26.33 cm

hintHint:

tan 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: 7.44 cm


    tan space 28 equals x over 14
equals greater than x equals tan space 28 cross times 14
equals greater than x equals 0.5317 cross times 14
equals greater than x equals 7.4439
equals greater than x equals 7.44 space c m
