<h3>  What is trigonometry?</h3>

Trigonometry is the branch of geometry that gives the relationship between the angles and sides of a triangle.

c) proof. if cos∅ = \frac{x}{\sqrt{x^{2} + y^{2}  } }<em>,  </em>then x = adjacent, \sqrt{x^{2} + y^{2} } = hypotenuse

  To solve for opposite, since it is a right angle triangle

   hypotenuse^{2} = opposite^{2} + adjacent^{2}

  (\sqrt{x^{2}  + y^{2} }) ^{2} = opposite^{2} + x^{2}

  opposite^{2} = x^{2} +y^{2} -x^{2}

   opposite = y

xsin∅ = x(\frac{y}{\sqrt{x^{2}  + y^{2} } }) = \frac{xy}{\sqrt{x^{2} } + y^{2}  }

ycos∅ =  \frac{xy}{\sqrt{x^{2} } + y^{2}  }

Therefore xsin∅ = ycos∅

d) 41 sin∅ = 40

   sin∅ = 40/41

   solving for adjacent = 9

    tan ∅ = opp/adj = 40/9

\frac{tan \alpha }{tan^{2}\alpha  - 1 } = 40/9 ÷ (\frac{40}{9} )^{2} - 1 = 40/9  ÷ 1600/81 - 1

                                         = 40/9  ÷ 1519/81 = 40/9 x 81/1519 = 360/1519

e) 1 - cos ∅ = 1/2

    cos ∅  = 1 - 1/2 = 1/2

   ∅ = cos inverse of 0.5 = 60°

   tan 60 = \sqrt{3}    tan^{2} 60 = 3, sin 60 = \frac{\sqrt{3} }{2} sin^{2} 60 = 3/4

      tan^{2} 60 +  4sin^{2} 60 = 3 + 4(3/4) = 3 + 3 = 6

Area of this? and explanation if possible
Ivenika [448]
First you find the area of the square. 60 x 60 = 3600. Then, you find the area of the triangles. 60 x 20 = 1200. Divide 1200 by two: 600. 3600 + 1200 = 4800. The area of the shape is 4800.
