Mila [183]

Answer:

\dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

Step-by-step explanation:

\dfrac{\frac{1}{x^2}+\frac{2}{y}}{\frac{5}{x}-\frac{6}{y^2}} =

To eliminate the denominators of the main numerator and denominator, we multiply the numerator and denominator of the main fraction by the LCD of all small denominators.

The LCD of x^2, y, x, and y^2 is x^2y^2.

= \dfrac{x^2y^2 \times (\frac{1}{x^2}+\frac{2}{y})}{x^2y^2 \times (\frac{5}{x}-\frac{6}{y^2})}

= \dfrac{y^2 + 2x^2y}{5xy^2 - 6x^2}

= \dfrac{y(y + 2x^2)}{x(5y^2 - 6x)}

= \dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

A triangle needs to add up to 180 degrees so 44 plus 37 is 81 so that last angle is 99 degrees then you do 180 minus that angle because those 2 angles need to equal up so not equals 81
