\frac{a}{ \sin(a) }  =  \frac{b}{ \sin(b)  }
\frac{12}{ \sin(38) }  =  \frac{b}{ \sin(85) }
\frac{12}{ \sin(38) }  =  \frac{a}{ \sin(57) }
180 - (85 + 38) = 57
\frac{12}{ \sin(38) }  =  \frac{b}{ \sin(85) }
\sin(85)   \times  \frac{12}{ \sin(38) }  = b
\sin(57)   \times  \frac{12}{ \sin(38) }  = a
sorry for the order of steps

Is this right? and do you use not use the x-intercepts?
vampirchik [111]

Answer:

You are correct.

Step-by-step explanation:

The x-intercept could be written the way you have or also it can be written as a point (-1, 0).

The y-intercept could also be written as a point (0, -2) But they are commonly written the way you have also.

So, the slope is -2. But just to be clear. That slope of -2 has nothing to do with the y-intercept of -2.

If you mark all the points on the line, to get from one point to the next point, you go down 2 and over (positive direction) 1. The down 2 in math is -2 and the over 1 is just 1. The slope is that ratio of -2/1.

Slope tells us if the line is going up or down, steep or flat, even horizontal. It was coincidence only that the y-intercept and slope were the same number.

  • siny=s/8
  • tany=s/t

\\ \tt\longmapsto cosy=\dfrac{siny}{tany}

\\ \tt\longmapsto cosy=\dfrac{s/8}{s/t}

\\ \tt\longmapsto cosy=8/t

  • Secy=1/cosy=t/8

Helpp pls????????????
Jet001 [13]

Answer:

It just means that it is not equal to each other so the equation is false.

Step-by-step explanation:

The equal sign with a line through it means that they aren't the same. -12 is a different number from 12 so they can't end up being the same in the end of the equation.

Hope this helps!
