First we need to define our conditions. Since the angles are complimentary, the sum of the angles must be equal to 90 degrees.

let x = first angle
y = second angle

x + y = 90

from the second condition in the problem 

x + y =72 + x -y
solving for x

x= 54

therefore the shorter side is 90 - 54 = y

y = 36 degree, the shorter side

Find the area. Around your answer to decimal places​
alexgriva [62]
  • Answer:

<em>86.20 ft²</em>

  • Step-by-step explanation:

<em>Hi there !</em>

<em>A = A₁ + A₂</em>

<em>A₁ =semicircle</em>

<em>A₁ = πr²/2</em>

<em>r = d/2 = 6.4ft/2 = 3.2 ft</em>

<em>A₁ = 3.14×(3.2ft)²/2 ≈ 32.15 ft²</em>

<em />

<em>A₂ =  trapezium</em>

<em>A₂ = (b + B)×h/2</em>

<em>A₂ = (5.1ft + 6.4ft)×9.4ft/2 = 54.05 ft²</em>

<em />

<em>A = 32.15 ft² + 54.05 ft² = 86.20 ft²</em>

<em>Good luck !</em>
