The answer to this question is $6. When you divide 27 by 4.5, you get 6. In addition, 6 times 4.5 = 27. I hope this helped! Could I possibly get brainliest?

Multiply the probability by the cost of the accident:

14,886.05 x 0.071 = 1056.91

Now add the overhead cost:

1056.91 + 110 = 1166.91

The closest answer to this is number D.

Triangles add up to 180. So add up the two angles given, and subtract that from 180. That will be x!

If the angles are represented in degrees,find both angles: csc(2x+9) =sec(3x+26) Please respond quick

Olenka [21]

Answer:

Before solving the given trigonometric relation change everything to sines and cosines

Step-by-step explanation:

consider the given equation;

$1/sin(2x+9)$ = $1/cos(3x+26)$

Multiplying the above equation on both sides by $cos(3x+26)sin(2x+9)$ then we get,

$cos(3x+26)=sin(2x+9)$

By using identity, $cos a=sin(90-a)$ expand above equation we will get,

$sin(90-(3x+26))=sin(2x+9)$

Then,

$90-3x+26=2x+9$

$x=11$

So the required value of the angle is $11$ degree.
