Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following:
Katyanochek1 [597]

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.

__

<em>Additional comment</em>

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 circle E with diameter CD and
irina1246 [14]

The Pythagoras is the sum of the square of two sides equal to the square of the longest side. Then the value of AC is 24 units.

<h3>What is a circle?</h3>

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Given circle E with diameter CD and radius EA. AB is tangent to E at A.

If AD = 10 and CD = 26.

Then the value of AC will be

We know that the tangent and radius make 90 degrees. Then the triangle is a right-angle triangle.

Then the AC is given by the Pythagoras theorem.

B² = H² - P²

B² = 26² - 10²

B² = 576

 B = 24
