4.  all for angles need to equal 360
  90 +90 + 42 = 222
360-222 = 138
y = 138 degrees
 x - 42 degrees


6. x = arctan(8/4) = 63.43 degrees ( round as needed)
  y =  16 / tan(63) = 8.15 ( round as needed)

Write the slope intercept form through: (5,1) and(2, -2)
victus00 [196]

We see that the slope of this line is \frac{-2-1}{2-5}=1, so we plug this and the point (5,1) into the point-slope form y-y_1=m(x-x_1) (note that there's nothing special about the point I picked; you can choose any point on the line):

y-1=x-5. This rearranges to the slope-intercept form \boxed{y=x-4}.

How do you simplify cscx*secx-tanx?
kenny6666 [7]
Csc x · sec x - tan x = 
= 1 / sin x · 1 / cos x - sin x / cos x = 
= 1 / sinx cos x - sin² x / sin x cos x = 
= ( 1 - sin² x ) / (sin x cos x) =
=  cos² x / ( sin x cos x ) = 
= cos x / sin x = cot x

Solve the equation, <br>-3|6n-2|+5=8
Marianna [84]
Hey..... Nice to see you :)
Let me help you out.

-3|6n -2| + 5 = 8
-3|6n -2| = 8-5
-3|6n -2| = 3
|6n -2| = 3/-3
|6n -2| = -1
Now, solve absolute value
No solutions.

Because absolute value cannot be less than 0.


I hope that's help !
