Answer: Pythagorean theorem which a² + b² = c².

Step-by-step explanation: This is showing me with the information you have given me a pythagorean triple.

Exp: This is a common pythagorean triple (6,8,10)

6²+8²=10².

10 is the hypotenuse which is the longest and is across the 90 angle.

6²=36 and 8²=64 which if you add both numbers equal 100. 10² is 100. You know it is a common pythagorean since both sides have the same number.

Answer:

x^2+8^2=10^2

Step-by-step explanation:

Use Pythagorean theorem, which states that for legs of a right triangle a and b, and the hypotenuse of that triangle c,

a^2+b^2=c^2

Are the following lines parallel perpendicular or neither y=-5/3x - 5 and y=4/3x - 5

katrin [286]

Answer:

neither

Step-by-step explanation:

For lines to be parallels the slopes must be equal, for the lines to be perpendicular the lines have to be inverse reciprocals meaning if you have a slope of 1/2X then the perpendicular line must be -2X

An isosceles triangle’s altitude will bisect its base. Which expression could be used to find the area of the isosceles triangle

omeli [17]

Answer:

$\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}$

Step-by-step explanation:

The length of the base is the distance between the points 4+2i and 10+4i, so

$\text{Base}=|10+4i-(4+2i)|=|10+4i-4-2i|=|6+2i|=\sqrt{6^2+2^2}=\\ \\=\sqrt{36+4}=\sqrt{40}$

The middle point of the base is placed at point

$\dfrac{4+2i+10+4i}{2}=\dfrac{6i+14}{2}=7+3i$

The length of the height is the distance between the points 5+9i and 7+3i

$\text{Height}=|5+9i-(7+3i)|=|5+9i-7-3i|=|-2+6i|=\sqrt{(-2)^2+6^2}=\\ \\=\sqrt{4+36}=\sqrt{40}$

So, the area of the triangle is

$A=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}$
