A trigonometric expression is given to us and we need to simplify it and find out the value.

<em><u>Given</u></em><em><u> </u></em><em><u>Expression</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em>

\sf\implies 3(tan^2\theta - sec^2\theta )

<em><u>Using </u></em><em><u>Identity</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em>

\sf\implies sec^2\theta - tan^2\theta =1

So that ,

\sf\implies tan^2\theta -sec^2\theta = -1

<em><u>Substitute</u></em><em><u> the</u></em><em><u> </u></em><em><u>value</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em>

\sf\implies 3(tan^2\theta - sec^2\theta ) \\\\\sf\implies 3 *(-1) =\boxed{\red{\sf -3}}

<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>-</u><u>3</u><u> </u><u>.</u>

the area of a trapezoid is 36 square inches. The height is 4 inches and one bases twice the length of the other base. What are t
vlada-n [284]
The formula for this is A= \frac{1}{2} ( b_{1} + b_{2} )h.  Filling in accordingly, 36= \frac{1}{2}(x+2x)(4).  This simplifies to 36= \frac{1}{2}(3x)(4) and 36=6x.  Therefore, x = 6 so the bases are 6 and 12.
