Theorems about Special Segments in Triangles

**I need explaining my teacher can't explain good, she keeps putting me back. And using hard methods.To the dude that answer my first question, thanks for explaining it i can understand the other sums better**

**Refer to the figure below to find the measure.**

Thank you. Could you explain one the segment is parallel to one side of the triangle. Find the values of x and y . Just one please.

Hi zokura,

Look at your last question.You have a small triangle 12,15,10 and alarger similar triangle some factor larger. The factor is 45/15 =3 so the sides are 36,45,20.

Your answer didn't work hun, you can't explain anymore for me?

Hi zokura,

There was a typo in my answer. 3* 10 =30 not 20 and x = 2* 10 =20 or 30-10 = 20
