Question

Solve for x. Round to the nearest tenth.

  1. 11.1
  2. 9.3
  3. 13.0
  4. 5.5

hintHint:

cos space theta equals fraction numerator b a s e over denominator h y p o t e n u s e end fraction

The correct answer is: 9.3


    Here, x is the base and 11 is the hypotenuse.
    cos space 32 equals x over 11
equals greater than 0.848 equals x over 11
equals greater than x equals 0.848 space cross times 11
equals greater than x equals 9.328
    x=9.3 rounded off to the nearest tenth

    Identify the base and hypotenuse for solving the problem.
