10. A 50-ft ladder leans against a building so that the base of the ladder is 15 feet from the
Hunter-Best [27]

By applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°

<em><u>Recall:</u></em>

  • Trigonometry ratios that can be used to solve a right triangle are: SOH CAH TOA.
  • SOH represents: sin ∅ = Opp/Hyp
  • CAH represents: cos ∅ = Adj/Hyp
  • TOA represents: tan ∅ = Opp/Adj

The diagram attached below depicts the problem given.

∅ = x

Opp = 15 ft

Hyp = 50 ft

  • Thus, applying the trigonometry ratio, SOH, we have:

sin x = 15/50

x = sin^{-1}(15/50)

x = 17.5°

In conclusion, by applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°

o-na [289]

Answer:

Proportionality Constant = k = \frac{1}{9}

Step-by-step explanation:

Equation is:

y = \frac{x}{9}

=> y = (\frac{1}{9} ) x

Comparing it with y = kx, where k is the proportionality constant, We get:

Proportionality Constant = k = \frac{1}{9}
