How in the heck do I do this?​
Fudgin [204]

The measure of a triangle is 180 degrees. In other words the sum of the angles of a triangle is 180 degrees

To solve for x set all of the expressions of angles equal to 180 and isolate x

11x - 3 + 7x + 5 + 13x - 8 = 180

31x + (- 6 + 6) = 180 + 6

31x/31  = 186 / 31

x = 6

To find the measure of each angle plug 6 into the x into each individual expression

Hope this helped!

Please help! x^3 +y^3=9
Crank

Step-by-step explanation:

Taking the derivative of both sides with respect to x, we get

\dfrac{d}{dx}(x^3 + y^3) = \dfrac{d}{dx}(3)

\Rightarrow 3x^2 + 3y^2\dfrac{dy}{dx} = 0

Solving for \frac{dy}{dx}, we get

\dfrac{dy}{dx} = -\dfrac{3x^2}{3y^2} = -\dfrac{x^2}{y^2}
