A 40 yd polygon and 15 yd polygon are similar. find the area of their ratios
Lubov Fominskaja [6]
Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 = <span> <span> <span> 2.6666666667 </span> </span> </span> <span> <span> <span> 2.6666666667^2 = </span></span></span> <span> <span> <span> 7.1111111111
</span></span></span>
<span><span><span> </span> </span> </span> So, the 40 yard polygon has <span> <span> 7.1111111111</span>times the area of the 15 yard polygon.

How to do question 27
GenaCL600 [577]
1/(sin(90 + θ)cos(360 - θ))     -   tan²(-θ)

Note:

 sin(90 + θ) = cosθ        Cosine and Sine are complementary.

cos(360 - θ) = cosθ      Cosine positive in 4th quadrant.

tan(-θ) = -tanθ          Negative angle concept.


1/(sin(90 + θ)cos(360 - θ))     -   tan²(-θ) =  1/(cosθcosθ)     -   (-tanθ)²

                                                                 =  1/(cos²θ)     -       tan²θ

                                                                  =  (1/cosθ)²     -       tan²θ
Note: 1/cosθ = secθ

                                                                 =  (secθ)²     -       tan²θ

                                                                  =  sec²θ     -       tan²θ

                                                                  =  1


Note that    1+ tan²θ = sec²θ is a Trigonometric identity.

That means:  sec²θ     -       tan²θ = 1

Hope this explains it.
