Answer:

x = 2

y = 15

Step-by-step explanation:

As the triangle is split with a line that is parallel to the base:

\implies x:6=6:18

\implies \dfrac{x}{6}=\dfrac{6}{18}

\implies x=\dfrac{6\cdot 6}{18}

\implies x=\dfrac{36}{18}

\implies x=2

Similarly:

\implies y:20=6 : (6+x)

\implies y:20=6:8

\implies \dfrac{y}{20}=\dfrac68

\implies y=\dfrac{6 \cdot 20}{8}

\implies y=\dfrac{120}{8}

\implies y=15

Answer:

x= 5.18

y= 16.97

Step-by-step explanation:

Solve Y first-

trigonometric theorems-

c^2 =a^2 + b^2\\\\b^2 =c^2 - a^2

y^2 =18^2-6^2 \\y^2 =324 - 36\\y^2= 288\\\sqrt{2} = \sqrt{288} \\ y=16.97

solve x-

20-16.97=3.03

x=5.18

(I'm not sure if the answers are correct. I tried my best. I was confused to solve x though. )
