Classify the four angles of the quadrilateral

Answers

Answer 1

Answer:

<A = right angle

<B = acute angle

<C = obtuse angle

<D = acute angle

Step-by-step explanation:

Right angle = 90 degrees

Acute angle = less than 90 degrees

Obtuse angle = more than 90 degrees

Answer 2

∠A = 90° is a right angle, ∠B = 60° and ∠D = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

We have,

The quadrilateral ABCD.

There are four angles:

∠A = 90°
∠B = 60°

∠C = 140°

∠D = 70°

An acute angle is an angle whose measure is less than 90 degrees.

An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees.

A straight angle is an angle whose measure is 90 degrees.

Using the definition,

∠A = 90°

This is a right angle.
∠B = 60°

This is an acute angle.

∠C = 140°

This is an obtuse angle.

∠D = 70°

This is an acute angle.

Thus,

∠A = 90° is a right angle, ∠B = 60° and ∠D = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

I'm not sure and i need all teh help i can get, thanks

Answers

Answer:

Take the square root of a number that is not a perfect square. None of the numbers are perfect squares. After you do that you can do any closed operation you want with the resulting irrational and the two other rationals and you will end up with an irrational.

8*24*√5 is an example.

8+24+√5 is another

5*√8 + 24 is another.

If you take the cube root of any number that isn't a perfect cube you get an irrational, so you could take the cube root of 5 or 24 instead of the square root and do the same thing.

ANSWER THIS PLEASE!!!!

Answers

Given the points (0, -1) and (6, 1), we need the following information to solve for the equation of the line:

We need the slope and the y-intercept.

Let (x1, y1) = (0, -1)

(x2, y2) = (6, 1)

Substitute these values into the following slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - (-1)}{6 - 0} = \frac{1 + 1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]

Therefore, the slope (m) = 1/3.

Next, we need the y-intercept, (b), which is the point on the graph where it crosses the y-axis. It is also the value of the y-coordinate when its corresponding x-coordinate = 0.

Looking at one of the given points, (0, -1), this represents the y-intercept. Therefore, the y-intercept (b) = -1.

Now that we have our slope, m = 1/3, and y-intercept, b = -1, we can write our linear equation in slope-intercept form as:

y = 1/3x - 1
