2x =50 since it is an isosceles triangle

x =25

the sum of all angles in a triangle is 180

5y + 10 + 50 + 2x=180

5y + 10 + 50 +50 =180 because 2x = 50

combine like terms

5y +110 = 180

subtract 110 from each side

5y = 70

y = 14

Answer:

$x=\frac{2}{3} \pm \frac{1}{6}i \sqrt{158}$

Step-by-step explanation:

$18x^2-24x+87=0$

Using Quadratic Formula

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x=\frac{-\left(-24\right)\pm \sqrt{\left(-24\right)^2-4\cdot \:18\cdot \:87}}{2\cdot \:18}$

Solving the discriminant:

$\Delta = \left(-24\right)^2-4\cdot \:18\cdot \:87\\\Delta = 576-6264\\ \Delta=-5688$

$x= \frac{24 \pm \sqrt{-5688} }{36}$

$x= \frac{24 \pm \sqrt{5688i} }{36}$

Once $\sqrt{5688} =\sqrt{2^3\cdot \:3^2\cdot \:79}=6\sqrt{158}$

$x=\frac{24\pm6\sqrt{158}i}{36}$

Dividing the denominator and numerator by 6

$x=\frac{4\pm \sqrt{158}i}{6}$

Now rewrite it:

$x=\frac{4}{6} \pm i\frac{\sqrt{158}}{6}$

$x=\frac{2}{3} \pm i \frac{\sqrt{158}}{6}$

$x=\frac{2}{3} \pm \frac{1}{6}i \sqrt{158}$
