My estimated answer for 1 is x=1.59 or x=-1.26 and my exact answer is (in word form) x= 1 plus or minus the square root of 73 over 6. my estimated answer for 2 is x=-0.34 or x=1.74 and my exact answer (in word form) is x= -7 plus or minus the square root of 109 over -10. I took a picture of my work and hopefully you can read it

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle measure = 58°

Adjacent side of angle = <em>x</em>

Hypotenuse = 9

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [cosine]:                    cos58° = x/9
  2. Isolate <em>x</em>:                                     9cos58° = x
  3. Evaluate:                                     4.76927 = x
  4. Rewrite:                                      x = 4.76927
  5. Round:                                        x ≈ 4.8
