The trigonometric values for a right triangle can be obtained through the measurements of the different sides,
![\begin{gathered} sin(\theta)=\frac{op}{hyp} \\ cos(\theta)=\frac{ad}{hyp} \\ tan(\theta)=\frac{op}{ad} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20sin%28%5Ctheta%29%3D%5Cfrac%7Bop%7D%7Bhyp%7D%20%5C%5C%20cos%28%5Ctheta%29%3D%5Cfrac%7Bad%7D%7Bhyp%7D%20%5C%5C%20tan%28%5Ctheta%29%3D%5Cfrac%7Bop%7D%7Bad%7D%20%5Cend%7Bgathered%7D)
this can be found in a triangle like this,
then, identify the measurements in the given triangle
then,
First, we must understand what standard form of a line is. Standard form of a line is written like such that A,B, and C are all integers, and A must be positive. First, we must calculate the slope of the line that passes through theses coordinates.
<span>As a refresher, this is the equation to figure out the slope of two coordinates.Now, we just simplify the numerator and denominator. <span> </span></span>
The next step is to utilize point-slope form, which is where is a point on the line. Of course, we already know that (7,-3) and (4,-8) both lie of the line. Therefore, plug in one fot he coordinates. Once converted into point-slope, we must then convert into standard form. This is what is demonstrated in the next step.
<span>Let's multiply all sides by 3 to get rid of the fraction early.Distribute the 5 to both terms in the parentheses.Subtract 9 from both sides.Subtract 5x on both sides.We aren't done yet! The coefficient of the x-term must be positive. Therefore, divide by -1 on both sides.<span>This is standard form now, so we are done!</span></span>
Answer:
x = pi/2..only
Step-by-step explanation:
The equation states that...,
tan^2x.sin x = tan^2x
;we simplify the equation by dividing both sides by tan^2x...which then leaves our equation as,
; sin x = 1
; x = sin^-1 (1)
; Hence x = pi/2
C it makes the most sense
