<u>Trigonometry</u>

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

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

Angle θ = 64°

Opposite Leg = <em>x</em>

Hypotenuse = 11

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

  1. Substitute in variables [sine]:                                                                           \displaystyle sin(64^\circ) = \frac{x}{11}
  2. [Multiplication Property of Equality] Multiply 11 on both sides:                      \displaystyle 11sin(64^\circ) = x
  3. Rewrite:                                                                                                             \displaystyle x = 11sin(64^\circ)
  4. Evaluate:                                                                                                           \displaystyle x = 9.88673
  5. Round:                                                                                                               \displaystyle x \approx 9.9

Answer:

boys + girls =  45  -------(1)

There boys 17 more than girls, boys = girls + 17  ----------(2)

substitute (2) in (1)

girls + 17 + girls = 45

2 x girls + 17 = 45

2 x  girls = 45 - 17

2 x girls = 28

girls = 14

substitute in (2): boys = girls + 17 = 14 + 17 = 31
