Answer:

Thale's theorem stated that if a line parallel to the base of the triangle intersects it, the ratio of sides of the respective sides is equal

In this diagram, since the 2 horizontal lines are parallel

x/15 = 2/10

x = 30/10

x = 3

Is this a good math essay?
astra-53 [7]

Answer:

I'm just going to assume that your answer is correct since you didn't attach the question. If you are submitting this to your teacher then you are going to want to have correct spelling and grammar. The slang usage isn't professional, but if your teacher is fine with it then you should only worry about spelling. Hope this helped you!!
