Answer:

x = 20 / √3 = 20√3 / 3

Step-by-step explanation:

AC² = AD² + BC² = x² + x² = 2 x²

AF² = AC² + CF² = 2 x² + x² = 3 x²

3 x² = 20² = 400

x² = 400/3

x = 20 / √3 = 20√3 / 3

If the perimeter of Triangle XYZ is 56 cm, what is the perimeter of Triangle ABC?

Troyanec [42]

Answer:

28 cm

Step-by-step explanation:

Triangle ABC is obtained by joining the mid points of the sides of triangle XYZ.

So, perimeter of triangle ABC will be equal to half of the perimeter of triangle XYZ.

$P(\triangle ABC) = \frac{1}{2} \times P(\triangle XYZ)$

$P(\triangle ABC) = \frac{1}{2} \times 56$

$P(\triangle ABC) = 28\: cm$

Somebody please help me on multiple step equations with parenthesis.

mash [69]

Answer:

k = 8

Step-by-step explanation:

8(10 - k) = 2k

First, distribute within the parenthesis,

80 - 8k = 2k

Add 8k to both sides of the equation

80 = 10k

Divide both sides by 10 to get your answer

8 = k

I hope this helps :)
