Question

Solve for x. Round to the nearest tenth.

  1. 13.6
  2. 9.4
  3. 10.9
  4. 18.1

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: 9.4


    ssin space 46 equals x over 13
equals greater than x equals sin space 46 cross times 13
equals greater than x equals 0.71933 cross times 13
equals greater than x equals 9.3514
equals greater than x equals 9.34 space r o u n d e d space o f f space t o space t h e space n e a r e s t space t e n t h
