−10y+9x=−9 10y+5x=−5 ​
frozen [14]

Answer:

x = - 1 ;  y =0

Step-by-step explanation:

     −10y+9x= −9    --------------> EQU 1

       10y+5x= −5 ​    --------------> EQU 2

____________________

       0 + 14x = -14                     { add EQU 1 and EQU 2 }

                  x = -14/14

                   x = -1

Substitute the value of x in EQU 1;

-10y + 9 *(-1) = -9

-10y - 9  = -9

        -10y = -9 +9 = 0

             y = 0

Please help this question finding a side on a triangle
Masteriza [31]

Answer:

The side of the hypotenuse is 12.233 centimeters.

Step-by-step explanation:

The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:

\cos 56^{\circ} = \frac{7.4\,cm}{x} (1)

Where x is the length of the hypotenuse, measured in centimeters.

Then, we clear the variable within (1):

x = \frac{7.4\,cm}{\cos 56^{\circ}}

x = 13.233\,cm

The side of the hypotenuse is 12.233 centimeters.
