Use trig identities to transform the left side of the equation to the right side.
Taya2010 [7]

<u>Answer and explanation</u>

(1+sinθ)(1-sinθ)=cos²θ

We are to prove that the left hand side is equal to the right hand side.

(1+sinθ)(1-sinθ) = 1(1-sinθ) + sinθ(1-sinθ)

                         = 1 - sinθ + sinθ - sin²θ

                          = 1 - sin²θ

From the trigonometric identity sin²θ + cos²θ = 1,

1 - sin²θ = cos²θ

Each block in Ton's neighborhood is 3/8 mile long.If he walks four and 1/2 how far dose he walk
hram777 [196]

since each block is 3/8 of a mile, then how many miles in 4½?  well, it'd just be their product, but let's firstly convert the mixed fraction to improper.


\bf \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}}&#10;\\\\\\&#10;\cfrac{9}{2}\cdot \cfrac{3}{8}\implies \cfrac{27}{16}\implies 1\frac{11}{16}
