Help me do this problem.
ipn [44]

3\frac{5}{8} = \frac{29}{8}


\frac{1}{3}(3\frac{5}{8} )=(\frac{1}{3} (\frac{24}{8} ))+(\frac{1}{3} (\frac{5}{8} ))

[If you can't type fractions, then instead of 24/8, do 3]

The first missing value is 3 or \frac{24}{8}


= \frac{3}{3} + \frac{5}{24}

The second missing value is 24 (because 3 times 8 is 24)


= \frac{24}{24}+ \frac{5}{24}      Make the denominators the same in order to add them together

= \frac{29}{24}

The third missing value is 29

<u>Trigonometry</u>

  • [Right Triangles Only] SOHCAHTOA  
  • [Right Triangles Only] sinθ = opposite over hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Angle θ = A

Opposite Leg = 27

Hypotenuse = 42

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

  1. Substitute [sine]:                                                                                             sinA = 27/42
  2. Simplify:                                                                                                           sinA = 9/14
  3. Trig inverse:                                                                                                    A = sin⁻¹(9/14)
  4. Evaluate:                                                                                                         A = 40.0052°
  5. Round:                                                                                                             A ≈ 40°
