Explain why having three congruent angles in two triangles is not a good way to prove two

Mathematics

Marianna [84]3 years ago

Draw an equilateral triangle with side lengths of 1. Each angle here is 60 degrees, which is true of any equilateral triangle.

Now draw another equilateral triangle that has side lengths of 2 units. Clearly this triangle is not the same size as the previous one, but the angles are all still 60 degrees.

We have an example in which there are 2 triangles with the same angles, but the triangles are not congruent. Therefore, having info about congruent angles only isn't sufficient to prove triangles to be congruent.

Divide completely for the question below
juin [17]

Answer:

B) 5x^2

Step-by-step explanation:

\sqrt{\frac{50x^5}{2x} }

We can divide 50 by 2, we get 25 and we can cancel out x from x^5.

Therefore, we get

\sqrt{\frac{25x^4}{1} }

= √25x^4

When we take the square root of 25, we get 5 and √x^4 = x^2.

Taking the square root, we get

= 5x^2

Answer: B) 5x^2

Thank you.

For what values of a the following expressions are true: |a|=−a
Ymorist [56]

Answer:

Any negative number and 0 works for the expression.

Step-by-step explanation:

Looking at this type of equation, we know that either EVERY negative number and 0 or EVERY positive number and 0 will work for this equation, since nothing is being added and we're just working with absolutes/negatives.

Let's try a random positive number in the expression

|6| = -(6)\\6 \neq -6

So this positive number doesn't work, let's just test with another one.

|9| = -(9)\\9 \neq -9

So we know that positive numbers won't work with this expression.

Let's test 0 quickly, just to make sure.

|0| = -0\\0 = 0

So 0 works.

Let's try a few negative numbers now.

|-5| = -(-5)\\5 = 5

So yes, this does work. Let's try one more negative number.

|-120| = -(-120)\\120 = 120

This works. So, every negative number and 0 work with this equation.

Hope this helped!
