Triangle is both acute and scalene.

What is Triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

here, we have,

we know that,

A scalene triangle has three unequal sides and angles, whereas an acute triangle has three acute angles (measured fewer than 90 degrees). Consequently, the characteristics of an acute scalene triangle are as follows: three lines that cross each other. a trio of sharp angles All sides are not equal.

Given

All angles are less than 90 degrees so it is acute. The sides are of difference lengths so it is scalene.

It has 90 degrees so it's right
And none of the sides are equal so it's scalene

Half of a number decreased by 8 is 3

With the Brainly help you've gotten in the last 15 minutes or so,
you should be able to do this one now.

The mystery number . . . . . . .      M
Half of it . . . . . . . . . . . . . . . .  1/2 M
Half of it decreased by  8 . . .  1/2 M - 8

You said that's  3 .
So the equation you have to solve is

                                      1/2 M - 8  =  3

Add  8  to each side:      1/2 M       =  11

Multiply each side by  2 :      M       =  22

This is easier than the last one we ( I ) did.

Answers

The solution to the quadratic equation x² - 12x + 11 = 0 is x = 11 and x = 1.

What is the solution to the quadratic equation?

Given the quadratic equation in the question:

x² - 12x + 11 = 0

To solve the quadratic equation x² - 12x + 11 = 0 by completing the square, first the constant term to the other side of the equation:

x² - 12x + 11 = 0

x² - 12x + 11 - 11 = 0 - 11

x² - 12x = -11

Next, find the value that is equal to the square of half of b:

( b/2 )² = ( -12/2 )² = (-6)²

Add (-6)² to each side of the equation:

x² - 12x + (-6)² = -11 + (-6)²

x² - 12x + 36 = -11 + 36

x² - 12x + 36 = 25

Factor the perfect trinomial sqaure:

( x - 6 )² = 25

Solve for x:

x - 6 = ±√25

x - 6 = ±5

x = 6 ± 5

Hence, x = 6 - 5 = 1

And x = 6 + 5 = 11.

Therefore, the values of x are 1 and 11.
