A. Acute
B. Right
C. Obtuse

Given 6, 8, And 11 As The Three Sides Of A Triangle, Classify It As One Of The Following:A. AcuteB. RightC.

Answers

Answer 1

9514 1404 393

Answer:

  C. Obtuse

Step-by-step explanation:

The "form factor" I use for this is ...

  a^2 + b^2 - c^2 = 6^2 + 8^2 - 11^2 = 36 +64 -121 = -21

The value is negative, indicating an OBTUSE triangle.

__

Additional comment

In this expression, 'a' and 'b' are the two shortest sides (in no particular order) and 'c' is the longest side. The interpretation is ...

  negative — obtuse

  zero — right

  positive — acute

__

If you're familiar with Pythagorean triples, you know that the 3-4-5 right triangle triple can be doubled to give 6-8-10. The long side of 11 is longer than the hypotenuse for the right triangle, so would correspond to a largest angle greater than 90°. The 6-8-11 triangle would be OBTUSE.

Given 6, 8, And 11 As The Three Sides Of A Triangle, Classify It As One Of The Following:A. AcuteB. RightC.

translate in english please so we can answer

are these lines parallel, perpendicular, or neither?​

Answers

Answer:

[tex]\Huge\boxed{neither}[/tex]

Step-by-step explanation:

Parallel lines never touch and these lines intersect therefore these are not parallel lines

These lines may intersect but they do not create 90 degree angles which is essential for perpendicular lines and for those reasons the lines shown are not perpendicular lines

So we conclude that the lines shown are neither parallel lines nor perpendicular lines

In this problem...

The less than sign is pointing left, and the number is 4. We use an open circle because the sign is not equal to. If it was, we would of put a closed circle.

<, or > = Open circle (Not shaded)

≤, or ≥ = Closed circle (Shaded)

A cylinder has a base diameter of 8ft and a height of 20ft. What is it's volume in cubic ft, to the nearest 10th place?

Answers

Answer:

1005.3 ft³

Step-by-step explanation:

cylinder has a base diameter of 8ft and a height of 20ft. What is it's volume in cubic ft, to the nearest 10th place?

Given that:

Base diameter = 8feets

Radius, r = 8/2 = 4 feets

Height h, = 20 feets

Volume of cylinder, V = πr²h

V = π * 4² * 20

V = π * 16 * 20

V = 1005.3096

V = 1005.3096 ft³
