Question

4,09] BD является перпендикуляр треугольника ABC. XZ является перпендикуляр треугольника WXY. Треугольник ABC подобен треугольнику WXY с масштабным коэффициентом 1:3. Часть I. Найти BD, AB, WZ, XZ и WX. Часть II. Каков масштаб фактора периметры треугольника АВС и треугольник WXY? Показать все работы на оценку.

Спасибо!

Answer 1

Здравствуйте

Answer 2

You must help us out and write in English. Google Translate wants us to believe that lines might be perpendicular to triangles. Since this makes no sense, you're going to have to tell us what it actually means. It will be excellent practice for you.

Answer 3

"[4.09] BD is a perpendicular bisector of triangle ABC. XZ is a perpendicular bisector of triangle WXY. Triangle ABC is similar to triangle WXY with a scale factor of 1:3. Part I. Find BD, AB, WZ, XZ and WX. Part II. What is the scale factor of the perimeters of triangle ABC and triangle WXY? Show all work for credit."

Answer 4

English not too good,,

Answer 5

Здравствуйте?

English:
Hello?

Answer 6

Your translator is better than mine. I didn't get "bisector" at all.

There is not enough information. Are there any measurements given?

Answer 7

Здесь больше информации

Answer 8

Very Good.

AD = 7 implies (definition of bisector)

DC = 7

Similarity implies

WZ = ZY = 21

Do you see that this is so?

Answer 9

Let me tranlate,,,

Answer 10

Да я понимаю.

Answer 11

((I understand))))

Answer 12

Very good.

60º angle and right triangle, together, imply BD = \(7\sqrt{3}\)

30-60-90 Right Triangle is very helpful

Similarity implies XZ = \(21\sqrt{3}\)
